simplify (1/2 x-2)^2

Solution

simplify

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

Solution

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

Solution steps

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

\frac{1}{2} x = \frac{x}{2}

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

Apply Perfect Square Formula:

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

a = \frac{x}{2}, b = 2

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

Simplify

(\frac{x}{2})^{2} - 2 \cdot \frac{x}{2} \cdot 2 + 2^{2} : \frac{x ^{2}}{4} - 2 x + 4

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