That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (-5 plus or minus the square root of -15) divided by 2.
x = -2.5 + 1.9364916731037085i
x = -2.5 - 1.9364916731037085i
where i is the square root of negative one.

What is the factor expression of 10 plus 40?
I think you mean you want to pull the common factor(s) of 10 and 40 outside the expression 10 + 40. Since 40 is divisible by 10, 10 is clearly the gcf. So 10 + 40 = 10 * 1 + 10 * 4 =10 * (1 + 4).
