(x+2)(x-18)=0FIND THE SOLUTIONS OF THE EQUATION
2 answers:
Either one at any given time could be equal to zero. So
x + 2 = 0
x = - 2
x - 18 = 0
x = 18
I've enclosed a graph of this so you can see that the answers I've given are the ones expected.
(x + 2) (x - 18) = 0
x + 2 = 0 or x - 18 = 0
x = -2 or x = 18

Answer: x = -2 or x = 18
