Sagot :

Answer:

x²+2x-15=0

Step-by-step explanation:

Find the sum of the roots and the product of the roots.

-5+3=-2

-5(3)=-15

Make it into a quadratic equation

x²+2x-15=0

Why +2? Because we use the formula x²-b/a x + c/a=0 to make the quadratic equation. So :

x² - (-2/1)x + (-15)= 0

x²+2x-15=0

I hope it can help
