simplify 2(2x^3-1)^3-1

simplify

2 (2 x^{3} - 1)^{3} - 1

16 x^{9} - 24 x^{6} + 12 x^{3} - 3

Solution steps

2 (2 x^{3} - 1)^{3} - 1

Expand

2 (2 x^{3} - 1)^{3} : 16 x^{9} - 24 x^{6} + 12 x^{3} - 2

= 16 x^{9} - 24 x^{6} + 12 x^{3} - 2 - 1

Subtract the numbers:

- 2 - 1 = - 3

= 16 x^{9} - 24 x^{6} + 12 x^{3} - 3

\frac{( 5 x - x ^{2} + ( x - 5 ) ^{2} )}{( 10 x - 2 x ^{2} )}

\frac{a}{b} + \frac{b}{a} + 2

\frac{1 0 ^{5} + 1 0 ^{4} + 1 0 ^{3} - 5 x 1 0 ^{4}}{104}

(4 x - 8)^{3}

y + 5 (x^{8}) - 21
