expand (x+2)(x^2-7x+4)

expand

(x + 2) (x^{2} - 7 x + 4)

x^{3} - 5 x^{2} - 10 x + 8

Solution steps

(x + 2) (x^{2} - 7 x + 4)

Distribute parentheses

= x x^{2} + x (- 7 x) + x \cdot 4 + 2 x^{2} + 2 (- 7 x) + 2 \cdot 4

Simplify

x x^{2} + x (- 7 x) + x \cdot 4 + 2 x^{2} + 2 (- 7 x) + 2 \cdot 4 : x^{3} - 5 x^{2} - 10 x + 8

= x^{3} - 5 x^{2} - 10 x + 8

\frac{1}{3} \times (\frac{5}{3} + \frac{2}{5})

(x + 9) (4 x^{2} + 5 x + 6)

\frac{345}{180}

(3 m n^{2})^{4}
