HAWKES LEARNING SYSTEMS math courseware specialists Copyright © 2011 Hawkes Learning Systems. All rights reserved. Sum of Two Squares The sum of two squares is an expression of the form x 2 + a 2 and is not factorable. For example, x is the sum of two squares and is not factorable. There are no factors with integer coefficients whose product is x To understand this situation, write x = x 2 + 0x +36 and note that there are no factors of +36 that will add to 0.
