Question

find the values of the following polynomials at a = -2 and b=3.
a. a2+2ab+b2.
b. a3- 3a2b + 3ab2- b3​

Answer 1

Answer:

$\huge\boxed{\mathcal\pink{Answer}}$

Given polynomial is a 3−3a²b+3ab²−b³

Substituting the given values, we

get(−2)³ +3(−2)²(3)+3(−2)(3)² −(3)³

=−8+36−54−27

=−125
