expand (2a+3)(-2-a+5a^2)

expand

(2 a + 3) (- 2 - a + 5 a^{2})

10 a^{3} + 13 a^{2} - 7 a - 6

Solution steps

(2 a + 3) (- 2 - a + 5 a^{2})

Distribute parentheses

= 2 a (- 2) + 2 a (- a) + 2 a \cdot 5 a^{2} + 3 (- 2) + 3 (- a) + 3 \cdot 5 a^{2}

Simplify

2 a (- 2) + 2 a (- a) + 2 a \cdot 5 a^{2} + 3 (- 2) + 3 (- a) + 3 \cdot 5 a^{2} : 10 a^{3} + 13 a^{2} - 7 a - 6

= 10 a^{3} + 13 a^{2} - 7 a - 6

\frac{- 8}{10}

(x + y) (x^{2} + x y + y^{2})

2^{2} \cdot 2^{7} \cdot 2^{0}

(- 3) - 7

\frac{49}{20}
