expand (x+7)(x^2-3x+2)

expand

(x + 7) (x^{2} - 3 x + 2)

x^{3} + 4 x^{2} - 19 x + 14

Solution steps

(x + 7) (x^{2} - 3 x + 2)

Distribute parentheses

= x x^{2} + x (- 3 x) + x \cdot 2 + 7 x^{2} + 7 (- 3 x) + 7 \cdot 2

Simplify

x x^{2} + x (- 3 x) + x \cdot 2 + 7 x^{2} + 7 (- 3 x) + 7 \cdot 2 : x^{3} + 4 x^{2} - 19 x + 14

= x^{3} + 4 x^{2} - 19 x + 14

4 x^{2} + 12 + 9

\frac{a ^{\frac{2}{3}}}{b ^{\frac{1}{3}}} + \frac{b ^{\frac{2}{3}}}{a ^{\frac{1}{3}}}

32 + 42 - 2

(7 - 2 x)^{2}

- \frac{1}{8} + 1
