expand-3x^2(6x^2+2x-3)

expand

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

- 18 x^{4} - 6 x^{3} + 9 x^{2}

Solution steps

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

Apply the distributive law:

m (a + b + c) = ma + mb + m c

- 3 x^{2} (6 x^{2} + 2 x - 3) = - 3 x^{2} \cdot 6 x^{2} - 3 x^{2} \cdot 2 x - 3 x^{2} (- 3)

= - 3 x^{2} \cdot 6 x^{2} - 3 x^{2} \cdot 2 x - 3 x^{2} (- 3)

Simplify

- 3 x^{2} \cdot 6 x^{2} - 3 x^{2} \cdot 2 x - 3 x^{2} (- 3) : - 18 x^{4} - 6 x^{3} + 9 x^{2}

= - 18 x^{4} - 6 x^{3} + 9 x^{2}
