Identify A, B, C Quadratic Formula

• a = 2 , b = 3, c = -5

• a = 2, b = -3, c = 5

• a = 2, b = -3, c = -5

• a = -2, b = 3, c = 5

Solve Using the Quadratic Formula
 x² + 4x - 40 = -8

• -10 & -4

• -4 & 10

• -8 & 4

• 8 & -4

Use the quadratic formula to solve 2x² + 2x - 12?

• -2, 3

• 2, 3

• 2, -3

• -2, -3

In the equation
y = x² +5x +7, match each leading coefficient with its correct letter 

• a=0, b=5, c=7

• a=1, b=5, c=7

• a=7, b=5, c=1

What are a, b, and c in the quadratic?

• a = -5, b = 3, c = -10

• a = 5, b = 3, c = -10

• a = 5, b = -3, c = 10

• a = 5x², b = -3x, c = 10

• a = 4

  b = 8

  c = 3

• a = 4

  b = -8

  c = -3

• a = 4

  b = -8

  c = 3

• a = 4

  b = 8

  c = -3

What is the quadratic formula used for?

• To find the solutions or roots of a quadratic equation.

• To find the sum of two numbers.

• To calculate the area of a triangle.

• To determine the slope of a line.
