expand (3x+1)(3x^2+7x-7)

expand

(3 x + 1) (3 x^{2} + 7 x - 7)

9 x^{3} + 24 x^{2} - 14 x - 7

Solution steps

(3 x + 1) (3 x^{2} + 7 x - 7)

Distribute parentheses

= 3 x \cdot 3 x^{2} + 3 x \cdot 7 x + 3 x (- 7) + 1 \cdot 3 x^{2} + 1 \cdot 7 x + 1 \cdot (- 7)

Simplify

3 x \cdot 3 x^{2} + 3 x \cdot 7 x + 3 x (- 7) + 1 \cdot 3 x^{2} + 1 \cdot 7 x + 1 \cdot (- 7) : 9 x^{3} + 24 x^{2} - 14 x - 7

= 9 x^{3} + 24 x^{2} - 14 x - 7

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

(2 x + 3)^{6}

x^{3} + 3 x^{2} + 2 x - 6

9 x^{2} - y^{2} + 10 y - 25

6 4^{4} y^{2}
