expand 2x((2x+6)^2(x^2-9))

expand

2 x ((2 x + 6)^{2} (x^{2} - 9))

8 x^{5} + 48 x^{4} - 432 x^{2} - 648 x

Solution steps

2 x ((2 x + 6)^{2} (x^{2} - 9))

Remove parentheses:

(a) = a

= 2 x (2 x + 6)^{2} (x^{2} - 9)

(2 x + 6)^{2} = 4 x^{2} + 24 x + 36

= 2 x (4 x^{2} + 24 x + 36) (x^{2} - 9)

Expand

(4 x^{2} + 24 x + 36) (x^{2} - 9) : 4 x^{4} + 24 x^{3} - 216 x - 324

= 2 x (4 x^{4} + 24 x^{3} - 216 x - 324)

Expand

2 x (4 x^{4} + 24 x^{3} - 216 x - 324) : 8 x^{5} + 48 x^{4} - 432 x^{2} - 648 x

= 8 x^{5} + 48 x^{4} - 432 x^{2} - 648 x

(0, 32 - x) \cdot (6.3 - x)

((1 + 5 t)^{4} e^{2 + 2 t}) 5

(2 x + 3) e^{2}

\frac{7 x + 14}{( x + 3 ) ^{2}}

\frac{( x + 3 ) ( x + 2 )}{x + 5}
