Factored Form for Quadratic Functions

Standard form of a quadratic function is...

• y=ax²+bx+c

• y=ax+bx+c

• y=ax³+bx+c

• y=ax²+bx+cx

In factored form you can see the ______ of the graph easily.

• y-intercept

• vertex

• x-intercepts

Factor:
x² + 10x + 24

• (x + 8)(x + 3)
• (x + 6)(x + 4)
• (x + 12)(x - 2)
• (x + 12)(x + 2)

If your solution is x = 5, then your factor is

• (x + 5)

• 5x

• (x - 5)

• -5x
