Question

subtarct 4a² + 3a²b + ab² + b ³ from a³ + b³ + 3a²b + 7ab²​

Answer 1

Answer:

a³+b³+4a²+6a²b+8ab²+b³

Answer 2

Here's your answer...hope it helps!

$(a^{3} +b^{3} +3a^{2} b+7ab^{2} )-(4a^{2} +3a^{2} b+ab^{2} +b^{3} )$

$=(a^{3} +b^{3} +3a^{2} b+7ab^{2} )-4a^{2} -3a^{2} b-ab^{2} -b^{3}$

Grouping like terms together.

$= a^{3}-4a^{2} +b^{3}-b^{3}+3a^{2} b-3a^{2} b+7ab^{2} -ab^{2}$

$= a^{3} -4a^{2}+6ab^{2}$
