Question

Use the zero product property to find the solutions to the equation

Answer 1

2x2 – x – 15 = x(x + 1)
x2  - 2x - 15 = 0
(x - 5)(x + 3) = 0

x  = -3 , 5

Its C

Answer 2

Answer:

Step-by-step explanation:

We are given an equation , so we first need to simplify the equation

lets distribute the x on parenthesis first

$2x^2 -x- 15 = x^2 + x.$

Now bring all terms to the left so we get

$2x^2-x-15-x^2-x=x^2+x-x^2-x$

$x^2-2x-15=0$

Now since all terms are in one side , so we now factor the equation

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

Now apply the zero product property to get

x-5=0 or x+3=0

x=5 or x=-3

solution x=-3 or x=5
