to factor this equation you need to use the quadratic formula:
in this question a=1, b=1, c= -10
so after you plug in those number you answer would be:
x= (-1+ or - the square root of -39) divided by 2

The domain is what you choose it to be. You could, for example, choose the domain to be [3, 6.5] If the domain is the real numbers, the range is [-12.25, ∞).
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
