a^{2} - 4 a b + 4 b^{2} \div a^{2} - b^{2}

$a^{2} - 4 a b + 4 b^{2} \div a^{2} - b^{2}$

解题步骤 1

将除式重写为分数形式。

a^{2} - 4 a b + \frac{4 b^{2}}{a^{2}} - b^{2}

$a^{2} - 4 a b + \frac{4 b^{2}}{a^{2}} - b^{2}$

[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
