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

simplify

(2 x - 5)^{2}

4 x - 45 x + 5

Solution steps

(2 x - 5)^{2}

Apply Perfect Square Formula:

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

(2 x - 5)^{2} = (2 x)^{2} - 2 \cdot 2 x 5 + (5)^{2}

= (2 x)^{2} - 2 \cdot 2 x 5 + (5)^{2}

(2 x)^{2} = 4 x

- 2 \cdot 2 x 5 = - 45 x

(5)^{2} = 5

= 4 x - 45 x + 5

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

x^{\frac{1}{3}} (x - 4)

- 211 (4 + 37)

\frac{1}{s ( s + 2 )}

(e^{x} + 1) (e^{x} - 1)
