simplify (4-sqrt(x))^2

Solution

simplify

(4 - x)^{2}

Solution

16 - 8 x + x

Solution steps

(4 - x)^{2}

Apply Perfect Square Formula:

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

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

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

4^{2} = 16

- 2 \cdot 4 x = - 8 x

(x)^{2} = x

= 16 - 8 x + x
