expand (-2-x^{1/2})^2

expand

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

4 + 4 x^{\frac{1}{2}} + x

Solution steps

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

Apply Perfect Square Formula:

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

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

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

Simplify

(- 2)^{2} - 2 (- 2) x^{\frac{1}{2}} + (x^{\frac{1}{2}})^{2} : 4 + 4 x^{\frac{1}{2}} + x

= 4 + 4 x^{\frac{1}{2}} + x

\frac{( x + a ) ( x + b )}{( x + 22 ) ( x + 26 )}

- 0.1 + \frac{0.5 w ^{3} + 2.9 w ^{2} + 3.5 w + 1.1}{( - w + 1 ) ^{3}}

\frac{- 20 x ^{3} - 11 x ^{2} - 18 x - 8}{( 4 x ^{4} - 4 ) ( x ^{2} + 1 )}

\frac{( y - 1 ) ( 27 y ^{2} + 1 )}{( 3 y - 1 ) ( 9 y ^{2} + 3 y + 1 )}
