expand (3x-1)(3x^2+4x-5)

expand

(3 x - 1) (3 x^{2} + 4 x - 5)

9 x^{3} + 9 x^{2} - 19 x + 5

Solution steps

(3 x - 1) (3 x^{2} + 4 x - 5)

Distribute parentheses

= 3 x \cdot 3 x^{2} + 3 x \cdot 4 x + 3 x (- 5) - 1 \cdot 3 x^{2} - 1 \cdot 4 x - 1 \cdot (- 5)

Simplify

3 x \cdot 3 x^{2} + 3 x \cdot 4 x + 3 x (- 5) - 1 \cdot 3 x^{2} - 1 \cdot 4 x - 1 \cdot (- 5) : 9 x^{3} + 9 x^{2} - 19 x + 5

= 9 x^{3} + 9 x^{2} - 19 x + 5

5 (3 - 4 k)

\frac{4}{9} \times \frac{3}{8}

\frac{8 x + 5}{2 x - 3} - \frac{7 x + 1}{2 x - 3}

2 (3 + 2) - 6

(- 5 f + 9) - (- 2 f + 8)
