expand (x+6)(3x^2+4x-3)

expand

(x + 6) (3 x^{2} + 4 x - 3)

3 x^{3} + 22 x^{2} + 21 x - 18

Solution steps

(x + 6) (3 x^{2} + 4 x - 3)

Distribute parentheses

= x \cdot 3 x^{2} + x \cdot 4 x + x (- 3) + 6 \cdot 3 x^{2} + 6 \cdot 4 x + 6 (- 3)

Simplify

x \cdot 3 x^{2} + x \cdot 4 x + x (- 3) + 6 \cdot 3 x^{2} + 6 \cdot 4 x + 6 (- 3) : 3 x^{3} + 22 x^{2} + 21 x - 18

= 3 x^{3} + 22 x^{2} + 21 x - 18

8 x

- 3 x^{2} (7 x^{2} - x + 4)

(\frac{5}{7})^{10} \cdot 1. 4^{9}

\frac{3}{4 v ^{2} + 4 v} - \frac{7}{2}

(1 - i 3)^{- 4}
