expand (3a+2)(4a^2-2a+9)

expand

(3 a + 2) (4 a^{2} - 2 a + 9)

12 a^{3} + 2 a^{2} + 23 a + 18

Solution steps

(3 a + 2) (4 a^{2} - 2 a + 9)

Distribute parentheses

= 3 a \cdot 4 a^{2} + 3 a (- 2 a) + 3 a \cdot 9 + 2 \cdot 4 a^{2} + 2 (- 2 a) + 2 \cdot 9

Simplify

3 a \cdot 4 a^{2} + 3 a (- 2 a) + 3 a \cdot 9 + 2 \cdot 4 a^{2} + 2 (- 2 a) + 2 \cdot 9 : 12 a^{3} + 2 a^{2} + 23 a + 18

= 12 a^{3} + 2 a^{2} + 23 a + 18

4 a + 8

\frac{2}{6} + \frac{2}{6}

\frac{6.59}{e ^{\frac{0.698}{0.026}} - 1}

(3 + 3)^{2}

e^{0} - 0
