expand (x^2+x-6)(2x^2+4x)

expand

(x^{2} + x - 6) (2 x^{2} + 4 x)

2 x^{4} + 6 x^{3} - 8 x^{2} - 24 x

Solution steps

(x^{2} + x - 6) (2 x^{2} + 4 x)

Distribute parentheses

= x^{2} \cdot 2 x^{2} + x^{2} \cdot 4 x + x \cdot 2 x^{2} + x \cdot 4 x - 6 \cdot 2 x^{2} - 6 \cdot 4 x

Simplify

x^{2} \cdot 2 x^{2} + x^{2} \cdot 4 x + x \cdot 2 x^{2} + x \cdot 4 x - 6 \cdot 2 x^{2} - 6 \cdot 4 x : 2 x^{4} + 6 x^{3} - 8 x^{2} - 24 x

= 2 x^{4} + 6 x^{3} - 8 x^{2} - 24 x

(4 x + 1) (5 x - 2)

\frac{1}{x + 3} - 5

(5^{2}) (5^{8})

(- 4 m^{2} b) (- 5 m^{3} b)

1 0^{2.5}
