expand (6/7-x)^2

Solution

expand

(\frac{6}{7} - x)^{2}

Solution

\frac{49 x ^{2} + 36 - 84 x}{49}

Solution steps

(\frac{6}{7} - x)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(\frac{6}{7} - x)^{2} = (\frac{6}{7})^{2} - 2 \cdot \frac{6}{7} x + x^{2}

= (\frac{6}{7})^{2} - 2 \cdot \frac{6}{7} x + x^{2}

Simplify

(\frac{6}{7})^{2} - 2 \cdot \frac{6}{7} x + x^{2} : \frac{49 x ^{2} + 36 - 84 x}{49}

= \frac{49 x ^{2} + 36 - 84 x}{49}
