Question

Identify the solutions to the quadratic equation!

Answer 1

The solution to the quadratic equation are option C) x= -5 and option E) x=3.

Step-by-step explanation:

The given  quadratic equation is x²+2x-15 = 0.

Using the factorization method,

• product of the roots should be -15.
• Sum of the roots should be 2.

⇒ -15 = 5 $\times$ -3

⇒ 2 = 5+(-3)

(x+5)(x-3) = 0

Therefore, x = -5 and x = 3
