expand (3x^2-x-4)(3x^2+x+1)

expand

(3 x^{2} - x - 4) (3 x^{2} + x + 1)

9 x^{4} - 10 x^{2} - 5 x - 4

Solution steps

(3 x^{2} - x - 4) (3 x^{2} + x + 1)

Distribute parentheses

= 3 x^{2} \cdot 3 x^{2} + 3 x^{2} x + 3 x^{2} \cdot 1 - x \cdot 3 x^{2} - xx - x \cdot 1 - 4 \cdot 3 x^{2} - 4 x - 4 \cdot 1

Simplify

3 x^{2} \cdot 3 x^{2} + 3 x^{2} x + 3 x^{2} \cdot 1 - x \cdot 3 x^{2} - xx - x \cdot 1 - 4 \cdot 3 x^{2} - 4 x - 4 \cdot 1 : 9 x^{4} - 10 x^{2} - 5 x - 4

= 9 x^{4} - 10 x^{2} - 5 x - 4
