Understanding quadratic equations in one variable

What is the standard form for a quadratic ?

• y=0

• f(x)=mx+b

• ax^2+bx+c

• -b/2a

What form is the quadratic equation written in?
y = 2x² + 5x + 5

• Hege
• Vertex
• Standard
• Factored

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

Identify the 'c' value: y = 16x² -8x -24

• 16
• -8
• 24
• -24

In the equation

y = x² +5x +7

match each number with its correct letter.

• a=0, b=5, c=7

• a=1, b=5, c=7

• a=7, b=5, c=1

Write an equation in Factored Form, whose solutions are  $0$  and  $-\frac{7}{2}$  .

• y = x(2x + 7)

• y = x(2x - 7)

• y = x(7x + 2)

• y = x(7x - 2)

What is b? 3x²+17x+2

• 2

• 3

• 17

What is the standard form of a quadratic equation?

• y=x²
• ax²+bx+c = 0
• Ax + By = C
• y = mx + b

• a = 3 , b = -2, c = 6

• a = -3, b = 2, c = 6

• a = -3, b = -2, c = -6

• a = 3, b = 2, c = -6
