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

expand

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

3 x^{3} - 11 x^{2} - 9 x + 20

Solution steps

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

Distribute parentheses

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

Simplify

x \cdot 3 x^{2} + xx + x (- 5) - 4 \cdot 3 x^{2} - 4 x - 4 (- 5) : 3 x^{3} - 11 x^{2} - 9 x + 20

= 3 x^{3} - 11 x^{2} - 9 x + 20

- \frac{3}{0}

- 7 + 0.3 (- 4 x + 20) + 8.8 x

\frac{4}{12} \div \frac{2}{6}

lo g_{15} (89.5)

\frac{lo g _{10} ( 16 - x ^{2} )}{lo g _{10} ( 3 x - 4 )}
