Question

How do you multiply ${\left(x+h\right)}^3$?

Answer 1

Simplify the equation.

Given expression is ${\left(x+h\right)}^3$.

Note that ${\left(a+b\right)}^3=a^3+3a^{2}b+3a{b}^2+b^3$

Let $a=x\text{and}b=h$

So,${\left(x+h\right)}^3=x^3+3x^{2}h+3x{h}^2+h^3$.

Hence, the answer is ${\left(x+h\right)}^3=x^3+3x^{2}h+3x{h}^2+h^3$.
