Lesson on Solving Equations in Factored Form

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

Factor: x² + 11x + 24

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

Factor: x² - 6x - 27

• (x+3)(x+9)
• (x+3)(x-9)
• (x-3)(x+9)
• (x-3)(x-9)

Factor and solve: x²+9x+14=0

• x = 7, -2

• x = -7, - 2

• x = 14, 1

• x = 3, 3
