simplify (3-sqrt(x))^2

Solution

simplify

(3 - x)^{2}

Solution

9 - 6 x + x

Solution steps

(3 - x)^{2}

Apply Perfect Square Formula:

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

(3 - x)^{2} = 3^{2} - 2 \cdot 3 x + (x)^{2}

= 3^{2} - 2 \cdot 3 x + (x)^{2}

3^{2} = 9

- 2 \cdot 3 x = - 6 x

(x)^{2} = x

= 9 - 6 x + x
