Work Step by Step

We are given the expression $(5w+2)(2w-5)$. We can find the product of this expression using the FOIL method. First terms: $5w\times 2w=10w^{2}$ Outer terms: $5w\times-5=-25w$ Inner terms: $2\times 2w=4w$ Last terms: $2\times-5=-10$ Adding together: $10w^{2}+(-25w)+4w+(-10)=10w^{2}-25w+4w-10=10w^{2}-21w-10$
