(1+x)^3-(1-x)^3=2x^3

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

x = 0

Solution steps

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

Expand

(1 + x)^{3} - (1 - x)^{3} : 2 x^{3} + 6 x

2 x^{3} + 6 x = 2 x^{3}

Move

2 x^{3}

to the left side

6 x = 0

Divide both sides by

6

x = 0

0.5 x + 4 + 0.9 x = x + 5

2 (3 x - 2) - (x + 3) = 8

(x - 3)^{2} - (x - 4)^{2} = 3

4.2 (5 x - 7) - 2.5 (2 - 4 x) = 120

\frac{x}{2} - \frac{6 - x}{4} = x + 1
