expand (3x^2-2x+2)(3x^2+2x-4)

expand

(3 x^{2} - 2 x + 2) (3 x^{2} + 2 x - 4)

9 x^{4} - 10 x^{2} + 12 x - 8

Solution steps

(3 x^{2} - 2 x + 2) (3 x^{2} + 2 x - 4)

Distribute parentheses

= 3 x^{2} \cdot 3 x^{2} + 3 x^{2} \cdot 2 x + 3 x^{2} (- 4) - 2 x \cdot 3 x^{2} - 2 x \cdot 2 x - 2 x (- 4) + 2 \cdot 3 x^{2} + 2 \cdot 2 x + 2 (- 4)

Simplify

3 x^{2} \cdot 3 x^{2} + 3 x^{2} \cdot 2 x + 3 x^{2} (- 4) - 2 x \cdot 3 x^{2} - 2 x \cdot 2 x - 2 x (- 4) + 2 \cdot 3 x^{2} + 2 \cdot 2 x + 2 (- 4) : 9 x^{4} - 10 x^{2} + 12 x - 8

= 9 x^{4} - 10 x^{2} + 12 x - 8

\frac{2 x ^{2} + 6 x}{10 x ^{3}}

7 (x - 2)

- 2 (n - 9) + 4

\frac{4 ^{3}}{4 ^{- 1}}
