simplify (sqrt(7-2x)-sqrt(x+2))^2

simplify

(7 - 2 x - x + 2)^{2}

- x - 2 7 - 2 x x + 2 + 9

Solution steps

(7 - 2 x - x + 2)^{2}

Apply Perfect Square Formula:

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

(7 - 2 x - x + 2)^{2} = (7 - 2 x)^{2} - 2 7 - 2 x x + 2 + (x + 2)^{2}

= (7 - 2 x)^{2} - 2 7 - 2 x x + 2 + (x + 2)^{2}

Simplify

(7 - 2 x)^{2} - 2 7 - 2 x x + 2 + (x + 2)^{2} : - x - 2 7 - 2 x x + 2 + 9

= - x - 2 7 - 2 x x + 2 + 9

(tan (x) + 1)^{2} cos (x)

sec (a) csc (a) (tan (a) + cot (a))

(1 + cos (a)) (1 - cos (a))

(x - \frac{1}{x})^{4}

\frac{1}{3} + \frac{2}{9} (0.9 - 1)
