What is the factored form of x²+16x+15

• (x+1)(x+15)

• (x+3)(x+5)

• (x-3)(x-5)

• (x-1)(x+15)

Factor: x² – 5x – 24

• (x - 5)(x + 19)

• (x - 8)(x + 3)

• (x - 3)(x + 8)

• (x - 19)(x + 5)

Answer explanation

To factor the quadratic expression x^2 - 5x + 6, we look for two numbers that multiply to 6 and add up to -5. These numbers are -2 and -3, so the factored form is (x - 2)(x - 3).

Solve the following quadratic equation:

5 = 2x² - 7x - 10​

(​ (a)   x ​ (b)   ​ (c)   )(x​ (d)   ​ (e)   )

• 2

• +

• 3

• -

• 5
