Question 55231
Please simplify
{{{(2b-2)(4b^2-2b-5)}}}  First distribute 2b, then distribute -2 through the second set of parenthsis.
{{{2b(4b^2)+2b(-2b)+2b(-5)-2(4b^2)-2(-2b)-2(-5)}}}
{{{8b^3-4b^2-10b-8b^2+4b+10}}}  Then combine like terms.  
{{{8b^3+(-4-8)b^2+(-10+4)b+10}}}
{{{highlight(8b^3-12b^2-6b+10)}}}
Happy Calculating!!!
