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

expand

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

3 x^{3} - 19 x^{2} + 17 x + 4

Solution steps

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

Distribute parentheses

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

Simplify

3 x x^{2} + 3 x (- 5 x) + 3 x (- 1) - 4 x^{2} - 4 (- 5 x) - 4 (- 1) : 3 x^{3} - 19 x^{2} + 17 x + 4

= 3 x^{3} - 19 x^{2} + 17 x + 4

100 x^{2} - z^{2}

\frac{63 x ^{6}}{- 7 x ^{2}}

\frac{7}{12}

(y - 4)^{3}

1 (- 1)
