expand (1/(1-2x))^2

Solution

expand

(\frac{1}{1 - 2 x})^{2}

Solution

\frac{1}{1 - 4 x + 4 x ^{2}}

Solution steps

(\frac{1}{1 - 2 x})^{2}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{1 ^{2}}{( 1 - 2 x ) ^{2}}

Apply rule

1^{a} = 1

1^{2} = 1

= \frac{1}{( 1 - 2 x ) ^{2}}

(1 - 2 x)^{2} = 1 - 4 x + 4 x^{2}

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