Given the factored equation:
(x-2) (x+10) = 13
Determine the solution.
Solution:
Since the given is on factored form, we can simply equate each values on the parenthesis by zero in order to determine the solution. 13 will become zero since it was factored out without any corresponding variable.
x-2 = 0
transpose -2 on the other side of the equation, note that when transposing a number the sign changes.
x= 2
x + 10 = 0
x = - 10
The solutions for the given equation is x = 2, and x = -10
