expand (k+8)(3k^2-5k+7)

expand

(k + 8) (3 k^{2} - 5 k + 7)

3 k^{3} + 19 k^{2} - 33 k + 56

Solution steps

(k + 8) (3 k^{2} - 5 k + 7)

Distribute parentheses

= k \cdot 3 k^{2} + k (- 5 k) + k \cdot 7 + 8 \cdot 3 k^{2} + 8 (- 5 k) + 8 \cdot 7

Simplify

k \cdot 3 k^{2} + k (- 5 k) + k \cdot 7 + 8 \cdot 3 k^{2} + 8 (- 5 k) + 8 \cdot 7 : 3 k^{3} + 19 k^{2} - 33 k + 56

= 3 k^{3} + 19 k^{2} - 33 k + 56

\frac{v ^{2} - 3 v - 40}{v ^{2} - 11 v + 24}

210 \div 1 \frac{1}{3}

\frac{4 x ^{3} + 16 x ^{2} + 23 x + 20}{2 x + 5}

1 + \frac{3}{4} + \frac{4}{7}
