expandir 2x(ax)+6x^2(bx)+12x^2(cx)

Solução

expandir

2 x (a x) + 6 x^{2} (b x) + 12 x^{2} (c x)

2 a x^{2} + 6 b x^{3} + 12 c x^{3}

Passos da solução

2 x (a x) + 6 x^{2} (b x) + 12 x^{2} (c x)

Remover os parênteses:

(a) = a

= 2 x a x + 6 x^{2} b x + 12 x^{2} c x

2 x a x = 2 a x^{2}

6 x^{2} b x = 6 b x^{3}

12 x^{2} c x = 12 c x^{3}

= 2 a x^{2} + 6 b x^{3} + 12 c x^{3}
