GCF Identification in Structural Load Modeling

A facilities engineer is reviewing a structural load model represented by the polynomial expression x2+2x−5x−10x^2 + 2x - 5x - 10. To factor this expression by grouping, the engineer organizes the terms into two pairs: (x2+2x)(x^2 + 2x) and (−5x−10)(-5x - 10). Based on the standard process for factoring this specific polynomial, what is the Greatest Common Factor (GCF) that must be factored out of the second pair, (−5x−10)(-5x - 10), to leave the common binomial factor (x+2)(x + 2)?
