how do you distribute this: 2(x+h)squared+5x+2?

Answer 1

2(x+h)^2 + 5x + 2

(x + h)^2 = (x + h)(x + h) = xx + xh + hx + hh = xx + 2xh + hh
mulitply by 2
2(xx +2xh + hh)= 2xx + 4xh + 2hh
add everything together
2xx + 4xh + 2hh + 5x + 2
wee see 4xh and 5x have x in them. so we can combine these terms
2xx + (4h + 5)x + 2hh + 2

Answer 2

start here
2²(x²+h²)+5x+2
2*2=4 take that to 4(x²+h²)+5x+2
then 4(x*x+h*h)+5x+2
then 4(2x+2h)+5x+2
and so on to 8x+8h+5x+2
bla bla bla 13x+8h+2 i think it stop there.
but if not.
i think it goes to 13x+10h if thats right
it would go on to 13 over x - 10 over h thats as far as i got.
let me know what is rong with is and how far it realy goes.
also show your work.
