aspect the expression through grouping. First, the expression requirements to be rewritten as x^2+ax+bx+16. To find a and b, collection up a mechanism to be solved.

You are watching: Factor x^2-8


Since ab is positive, a and b have actually the same sign. Since a+b is negative, a and also b space both negative. List all together integer bag that provide product 16.
