What are the solutions to the equation? x2-14x=15 Enter your answers in the boxes. x = and

First put it in standard form:

x^2 - 14x - 15 = 0

a = 1 b = - 14 c=-15

Then use the quadratic formula:

x = [-b + - sq root (b^2 - 4ac) ] / 2a

x = [--14 + - sq root (14^2 - 4*1*-15] / 2*1

x = [14 + - sq root (196 + 60) ] / 2

x = [14 + - 16] / 2

x1 = 15

x2 = - 1
