anonymous · Answer

$$2(5x-4)(5x-4)$$in other words

anonymous · Answer

so i would take (10x^2-20x-20x+16) and multiply it by two to get 20x^2+80x+32?

anonymous · Answer

yes, except that that is not correct

anonymous · Answer

the first term is wrong since $5x\times 5x=25x^2$ and not $10x^2$

anonymous · Answer

hahah oooops. 5 x 5 is 25....

anonymous · Answer
