What is the quadratic formula?

The quadratic formula is x equals negative b plus or minus the square root of b squared minus 4ac, all over 2a. It is used to solve quadratic equations of the form ax^2 + bx + c = 0, where a, b, and c are constants and a is not equal to zero.

How do you find the slope of a line using two points?

To find the slope of a line using two points, you can use the formula: (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. Subtract the y-coordinates and divide by the difference in the x-coordinates to determine the slope of the line passing through those two points.

What is the difference between a rational and an irrational number?

A rational number can be expressed as a ratio of two integers (a fraction), whereas an irrational number cannot be expressed as a ratio of two integers and has an infinite non-repeating decimal expansion. In other words, rational numbers can be represented as quotients of integers, while irrational numbers cannot and have non-terminating, non-repeating decimal representations.

How do you simplify an algebraic expression?

To simplify an algebraic expression, you need to combine like terms by performing operations such as addition, subtraction, multiplication, and division. Start by grouping terms with the same variables raised to the same power, then combine them by adding or subtracting their coefficients. Finally, perform any necessary operations like distributing or factoring to further simplify the expression. Keep applying these steps until you have simplified the expression as much as possible.

What are the properties of exponents?

Exponents have several key properties, including 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), the negative exponent rule (a^(-n) = 1/(a^n)), and the reciprocal rule (1/a^n = a^(-n)). Exponents also follow the properties of addition, subtraction, and multiplication when dealing with multiple terms raised to an exponent.

How do you find the volume of a rectangular prism?

To find the volume of a rectangular prism, you would multiply the length, width, and height of the prism together. This formula for volume is expressed as V = l x w x h, where V represents the volume, l is the length, w is the width, and h is the height of the prism. Simply plug in the values for these dimensions and perform the calculation to determine the volume of the rectangular prism.

How do you calculate the area of a triangle?

The area of a triangle can be calculated using the formula: 1/2 x base x height, where base is the length of the bottom side of the triangle, and height is the perpendicular distance from the base to the opposite vertex. Simply multiply the base by the height and then divide the result by 2 to get the area of the triangle in square units.

What is the Pythagorean theorem?

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In mathematical terms, a² + b² = c², where 'c' is the length of the hypotenuse, and 'a' and 'b' are the lengths of the other two sides of the triangle.

How do you graph linear inequalities on a coordinate plane?

To graph linear inequalities on a coordinate plane, first rewrite the inequality in slope-intercept form (y = mx + b). Next, plot the line using the y-intercept (b) and the slope (m). If the inequality is greater than (>) or less than (<), use a dashed line to represent the boundary. If the inequality is greater than or equal to (?) or less than or equal to (?), use a solid line to represent the boundary. Finally, choose a test point not on the boundary line to determine which side of the line should be shaded to show the solution region. Shade the appropriate side and label it according to the inequality sign.

How do you compute the probability of an event?

To compute the probability of an event, you divide the number of favorable outcomes by the total number of possible outcomes. This is typically represented as P(event) = number of favorable outcomes / total number of outcomes. The probability of an event ranges from 0 (impossible event) to 1 (certain event), with values in between representing likelihoods.
