expand x^2(x+1)^3

Solution

expand

x^{2} (x + 1)^{3}

Solution

x^{5} + 3 x^{4} + 3 x^{3} + x^{2}

Solution steps

x^{2} (x + 1)^{3}

Expand

(x + 1)^{3} : x^{3} + 3 x^{2} + 3 x + 1

= x^{2} (x^{3} + 3 x^{2} + 3 x + 1)

Distribute parentheses

= x^{2} x^{3} + x^{2} \cdot 3 x^{2} + x^{2} \cdot 3 x + x^{2} \cdot 1

Simplify

x^{2} x^{3} + x^{2} \cdot 3 x^{2} + x^{2} \cdot 3 x + x^{2} \cdot 1 : x^{5} + 3 x^{4} + 3 x^{3} + x^{2}

= x^{5} + 3 x^{4} + 3 x^{3} + x^{2}
