Non-linear equations (one variable)

When in standard form, what is the value of a, b and c in this quadratic?

9x² + 4x - 6 = -5x + 8

• a = 14 b = 4 c = -14

• a = 9 b = 9 c = -14

• a = 9 b = -1 c = 2

• a = 9 b = -9 c = 14

Factored Form of a quadratic equation is y =

• (x + a)(x + b)

• ax² + bx + c

• (x - h)² + k

• mx + b

• Constants

• Coefficients

• Variables

Identify a, b, and c:  -2x + x² - 12 = 0

• a = -2, b = 1, c = -12
• a = 2, b = 1, c = 12
• a = 1, b = -2, c = -12
• a = 1, b = 2, c = 12

Which form is the equation in?

y = -3(x-5)²+7

• Standard

• Vertex

• Factored

• None of These

In the equation

-5x² + 4x - 7 = 12x - 3

identify a, b, and C

• a = -5, b = -8, c = -4

• a = 5, b = -8, c = -4

• a = -5, b = 16, c = -4

• a = -5, b = 16, c = -10

Find the a, b, and c:  $9x^2-4x+2=0$  

• a = 9, b = -4, c = 2

• a = 81, b = -4, c = 2

• a = 81, b = 4, c = 2

• a = 9, b = 4, c = 2

 $ax^2+bx+c$  is called _____________. 

• standard form

• slope intercept form

• weird form

• vertex form

Using the quadratic expression below, type the coefficient that represents c.
