Quadratic Functions (Zeroes & Forms)

Find the zero(s) of the function.

• x = 1
• x = -3
• x = {-1, 3}
• x = 2

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

• (x + 5)

• 5x

• (x - 5)

• -5x

If a quadratic function is represented as f(x) = (x - 7)(x + 8), find the zeroes.

• x = - 7 and x = 8

• x = 7 and x = -8

Solve by factoring: x² + 3x - 18 = 0

• x = -3 and x = 6
• x = 3 and x = -6
• x = -9 and x = 2
• x = 9 and x = -2

Convert x²+6x+9 to factored form and identify the solution.

• (x+3)(x+3); x=-3
• (x+4)(x+5); x=-4, -5
• (x-3)(x-3); x=3
• Not factorable
