expand (3x^2-12x)(x^2-2x+1)

expand

(3 x^{2} - 12 x) (x^{2} - 2 x + 1)

3 x^{4} - 18 x^{3} + 27 x^{2} - 12 x

Solution steps

(3 x^{2} - 12 x) (x^{2} - 2 x + 1)

Distribute parentheses

= 3 x^{2} x^{2} + 3 x^{2} (- 2 x) + 3 x^{2} \cdot 1 - 12 x x^{2} - 12 x (- 2 x) - 12 x \cdot 1

Simplify

3 x^{2} x^{2} + 3 x^{2} (- 2 x) + 3 x^{2} \cdot 1 - 12 x x^{2} - 12 x (- 2 x) - 12 x \cdot 1 : 3 x^{4} - 18 x^{3} + 27 x^{2} - 12 x

= 3 x^{4} - 18 x^{3} + 27 x^{2} - 12 x
