I really need help with this Simplify: (2x + y)(4x2 – 2xy + y2) If x=2 and y= 3
so what i would do is substitute x for 2 and y for 3 in each spot. after you do that it would look like (2(2)+3)(4(2)2-2(2)(3)+(3)2)
would it be something like this? 8x3 + y3.
(4+3)(16-10+6) is what i got after i substituted (7)(12) after i did what's in the parenthasis *sorry for bad spelling* then you should end up with 84 as your final result
if my math is correct
Ok i get that thank you
you're welcome :)
