expand (b+3)(b^2+2b+1)

expand

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

b^{3} + 5 b^{2} + 7 b + 3

Solution steps

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

Distribute parentheses

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

Simplify

b b^{2} + b \cdot 2 b + b \cdot 1 + 3 b^{2} + 3 \cdot 2 b + 3 \cdot 1 : b^{3} + 5 b^{2} + 7 b + 3

= b^{3} + 5 b^{2} + 7 b + 3

cot (x) + \frac{sin ( x )}{1 + cos ( x )}

7 \frac{1}{5}

2 x^{2} - 8 x + 4
