Question

Help! Put the polynomial in standard form. Show work.
(x2 + 4x – 3)(2x2 + x + 6)

Answer 1

\[(x^2+4x-3)(2x^2+x+6)\]distribute~ long work >.<
\[x^2(2x^2+x+6)+4x(2x^2+x+6)-3(2x^2+x+6)\]
\[2x^4+x^3+6x^2+4x^3+4x^2+24x-6x^2-3x-18\]
\[2x^4+5x^3+4x^2+21x-18\]
i thinkkkkkkkkkk! double check last step please :x

Answer 2

how did you get 5x^3

Answer 3

\[\huge 2x^4+x^3+6x^2+4x^3+4x^2+24x−6x^2−3x−18 \]the previous one has x^3 and 4x^3 the 3 looked kinda like 2

Answer 4

2x^4 + 9x^3 + 4x^2 +21x - 18

Answer 5

OHHHHHHHHH I SEEEE ITTTT
