expand (b^3+b^2)(b^2+7b+4)

expand

(b^{3} + b^{2}) (b^{2} + 7 b + 4)

b^{5} + 8 b^{4} + 11 b^{3} + 4 b^{2}

Solution steps

(b^{3} + b^{2}) (b^{2} + 7 b + 4)

Distribute parentheses

= b^{3} b^{2} + b^{3} \cdot 7 b + b^{3} \cdot 4 + b^{2} b^{2} + b^{2} \cdot 7 b + b^{2} \cdot 4

Simplify

b^{3} b^{2} + b^{3} \cdot 7 b + b^{3} \cdot 4 + b^{2} b^{2} + b^{2} \cdot 7 b + b^{2} \cdot 4 : b^{5} + 8 b^{4} + 11 b^{3} + 4 b^{2}

= b^{5} + 8 b^{4} + 11 b^{3} + 4 b^{2}

- 7 + \frac{6 ( - 8 x ) + 1}{- 8 x}

[x - 1 (x + 2)] - (3 x + 1)

\frac{5}{2} \cdot \frac{5}{4}

(3 \cdot 4)^{2 \cdot (- 1)}

(5^{- 2})^{- 2}
