Factor Quadratic Equations

Factor x² + 5x + 4

• (x + 1)(x + 4)

• (x + 5)(x + 1)

• (x + 2)(x + 3)

• (x + 5)(x - 1)

Factor
n²-13n+40

• (n-5)(n-8)

• (n+5)(n-8)

• (n-5)(n+8)

• (n+6)(n+1)

Factor the Trinomial:
x² - 8x + 15

• (x + 5) ( x + 3)

• (x - 5) (x - 3)

• (x + 15) (x - 1)

• (x - 7) (x - 8)

Solve the equation by factoring.

Which answer choice correctly shows the quadratic equation above in factored form?

• (x + 7)(x - 2) = 0

• (x - 7)(x + 2) = 0

• (x - 7)(x - 2) = 0

• (x + 7)(x + 2) = 0
