What is the quadratic formula?

The quadratic formula states that for a quadratic equation in the form of ax^2 + bx + c = 0, the solutions for x can be found using the formula: x = (-b ± ?(b^2 - 4ac)) / 2a.

How do you simplify algebraic expressions?

To simplify algebraic expressions, you typically combine like terms by adding or subtracting coefficients of the same variables. You can also use the distributive property to factor out common factors and simplify expressions. Additionally, you can apply rules of exponents to simplify terms with exponentials. Remember to follow the order of operations (PEMDAS) to simplify expressions correctly.

What is the Pythagorean theorem used for?

The Pythagorean theorem is used to calculate the length of the sides of a right-angled triangle. It states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This theorem is fundamental in geometry and is used in various fields such as engineering, architecture, physics, and surveying to solve for unknown sides or angles in right triangles.

How do you find the slope of a line?

To find the slope of a line, you can use the formula: rise over run, which is the change in y-coordinates divided by the change in x-coordinates of two points on the line. Another method is to use the slope-intercept form of a linear equation (y = mx + b), where m represents the slope of the line. When the equation of the line is given in this form, you can directly identify the slope coefficient 'm'.

How do you solve equations with variables on both sides?

To solve equations with variables on both sides, start by simplifying both sides of the equation by combining like terms if possible. Then, move all the variable terms to one side of the equation and all the constant terms to the other side by using inverse operations. Finally, solve for the variable by isolating it on one side and simplifying further if needed. Remember to perform the same operation on both sides of the equation to maintain equality throughout the process.

What are the properties of exponents?

The properties of exponents include the product rule (a^m * a^n = a^(m+n)), the quotient rule (a^m / a^n = a^(m-n)), the power rule ((a^m)^n = a^(m*n)), the zero rule (a^0 = 1), and the negative exponent rule (a^(-m) = 1/a^m). These properties are essential for simplifying and solving exponential expressions and equations.

How do you factor polynomials?

To factor a polynomial, first look for any common factors that can be factored out. Then, use methods such as the distributive property, grouping, or special factoring formulas like the difference of squares or perfect square trinomial to further factor the polynomial. Factoring involves breaking down the polynomial into simpler, easily manageable expressions, allowing you to rewrite it as a product of simpler factors. Practice and familiarity with different factoring techniques will help you efficiently factor polynomials.

What are absolute value equations used for?

Absolute value equations are used to find the mathematical distance between a number and zero on a number line. They are common in various applications such as physics, engineering, economics, and computer science, where the magnitude or distance of a quantity is important. In algebra, absolute value equations help solve problems involving inequalities by providing a way to express the distance between two values, making them a powerful tool for solving equations involving variables.

How do you graph linear inequalities?

To graph linear inequalities, first treat the inequality as an equation and graph the corresponding line. Then, determine whether the inequality symbol (<, >, ?, ?) indicates a shaded region above or below the line. If the inequality is strict (<, >), use a dashed line to represent it; if it is inclusive (?, ?), use a solid line. Finally, shade the region that satisfies the inequality. The solution to the inequality will be the shaded region, which may be a half-plane or a bounded region on the coordinate plane.

What is the difference between dependent and independent events in probability?

Dependent events in probability are events where the outcome of one event affects the outcome of another event. In contrast, independent events are events where the outcome of one event does not affect the outcome of another event. The probability of two dependent events occurring is calculated by multiplying the probabilities of each event happening in succession, while the probability of two independent events occurring is calculated by multiplying the probabilities of each event happening separately.
