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

Solution

expand

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

Solution

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

Solution steps

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

Apply Perfect Square Formula:

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

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

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

1^{2} = 1

2 \cdot 1 \cdot x^{\frac{1}{2}} = 2 x^{\frac{1}{2}}

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

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