simplify (sqrt(x)-2sqrt(5))^2

simplify

(x - 25)^{2}

x - 45 x + 20

Solution steps

(x - 25)^{2}

Apply Perfect Square Formula:

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

(x - 25)^{2} = (x)^{2} - 2 x \cdot 25 + (25)^{2}

= (x)^{2} - 2 x \cdot 25 + (25)^{2}

(x)^{2} = x

- 2 x \cdot 25 = - 45 x

(25)^{2} = 20

= x - 45 x + 20

\frac{( x + 3 ) ( x - 2 )}{( x + 2 ) ( x - 1 )}

(e^{i x} - e^{- i x})^{2}

(x + 2) (2 - \frac{3}{x})^{6}

\frac{\partial}{\partial y} ((z) (4 x^{2} y + 3 y - 5))

(x + y - 1) d x - (2 x - y + 1) d y
