First simplify the expression into polynomial form,
Now factor into,
Which means the solutions are,
and then two complex solutions because determinant of the third factor ,
Hope this helps :)
Let's say, the amount that each side was increased was "a"
so, it was 5 wide and 12 long, now it's 5+a wide and 12+a long
we know the area is 120, so whatever "a" is, we know that
(5+a)(12+a) = 120
so
use those factors, solve for "a"
