Question 75283
{{{7w(2w -3)(2w + 3)}}}Start with the given problem
{{{7w(2w*2w+2w*3-3*2w-3*3)}}}First foil the 2 parenthesis
{{{7w(4w^2+cross(6w-6w)-9)}}}Subtract like terms. Notice the 6w terms cancel
{{{7w(4w^2-9)}}}
{{{7w*4w^2-7w*9}}}Distribute the 7w to each term
{{{28w^3-63w}}}There's the simplified answer.
