Quadratic Formula Standard Form

Write this equation x² -6 = x in standard form.

• x² +6x=0

• x² -6x=0

• x² -x -6 =0

• x² +x -6

Which equation is the standard form of a quadratic function?

• f(x) = mx + b

• f(x) = a(x - m)(x - n)

• f(x) = ax² + bx + c

• f(x) = a(x - h)² + k

The standard form of a quadratic function is

• y = ax² + bx + c

• a(x - h)² + k

• y - y₁ = m(x - x₁)

• Ax + By = C

Identify a, b, and c if y = +3x² +5x - 8

• a=3, b=5, c= - 8

• A=3, B=-8, C=5

• A=3x², B=5x, C=-8

• A=3x² , B=-8, C=5x
