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

x=5

Step-by-step explanation: x^2−2x−15=0

(x−5)=0                                                                                                                      x−5=0                                                                                                                             x=5                                                                                                                                                                                                              

You have to factor the equation and the way you do this is to find two numbers that multiply to get -15 and add to get -2 and those numbers are 3 and -5 so the factors are (x+3) and (x-5)

You set them equal to 0 and solve for x

x+3=0           x=-3

x-5=0            x=5

SO THERE YOU HAVE IT: x=5!

Have a nice day!!!
