One of the solutions to x2 - 2x - 15 = 0 is x = - 3. What is the other solution?

Ox=-5

Ox = - 1

0 x=1

x = 5

x=5

Step-by-step explanation:

Factoring x2 - 2x - 15 we get

(x+3) (x-5) so x+3=0 and x-5=0 or x=-3 and x=5

x=5

Step-by-step explanation:

x^2 - 2x - 15 = 0

Factor

What 2 numbers multiply to - 15 and add to - 2

-5*3 = - 15

-5+3 = - 2

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

Using the zero product property

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

x-5+5 = 0+5 x+3-3 = 0-3

x=5 x=-3
