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

expand

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

4 x^{3} + 11 x^{2} - 19 x + 4

Solution steps

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

Distribute parentheses

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

Simplify

4 x x^{2} + 4 x \cdot 3 x + 4 x (- 4) - 1 \cdot x^{2} - 1 \cdot 3 x - 1 \cdot (- 4) : 4 x^{3} + 11 x^{2} - 19 x + 4

= 4 x^{3} + 11 x^{2} - 19 x + 4

\frac{1}{x ^{2} + 3 x - 18} - \frac{4}{7 x ^{2} - 11 x - 30}

\frac{23}{10}

\frac{36}{24}

(6 + 10 i) - (1 + 7 i)

(3 x + 2) (2 x - 1)
