expand (a^{1/2}-b^{1/2})(a^{1/2}+b^{1/2})

expand

(a^{\frac{1}{2}} - b^{\frac{1}{2}}) (a^{\frac{1}{2}} + b^{\frac{1}{2}})

a - b

Solution steps

(a^{\frac{1}{2}} - b^{\frac{1}{2}}) (a^{\frac{1}{2}} + b^{\frac{1}{2}})

Apply Difference of Two Squares

(a^{\frac{1}{2}} - b^{\frac{1}{2}}) (a^{\frac{1}{2}} + b^{\frac{1}{2}}) : a - b

= a - b

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

(e^{t} - 2)^{2}

(5 - x) (5 + x)

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

(x + 1) (x + 2)
