expand (a^{9/2}-b^{9/2})^2

expand

(a^{\frac{9}{2}} - b^{\frac{9}{2}})^{2}

a^{9} - 2 a^{\frac{9}{2}} b^{\frac{9}{2}} + b^{9}

Solution steps

(a^{\frac{9}{2}} - b^{\frac{9}{2}})^{2}

Apply Perfect Square Formula:

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

(a^{\frac{9}{2}} - b^{\frac{9}{2}})^{2} = (a^{\frac{9}{2}})^{2} - 2 a^{\frac{9}{2}} b^{\frac{9}{2}} + (b^{\frac{9}{2}})^{2}

= (a^{\frac{9}{2}})^{2} - 2 a^{\frac{9}{2}} b^{\frac{9}{2}} + (b^{\frac{9}{2}})^{2}

(a^{\frac{9}{2}})^{2} = a^{9}

(b^{\frac{9}{2}})^{2} = b^{9}

= a^{9} - 2 a^{\frac{9}{2}} b^{\frac{9}{2}} + b^{9}

(sin (x))^{2} + (6 + cos (x))^{2}

(x^{2} + y^{2} + 1) \frac{d x}{d y}

\frac{12 x ^{2} - 31 x + 4}{( x - 4 ) ( x ^{2} + 2 )}

(x + 4 - 1)^{2}

\frac{1 - s - e ^{- s}}{s ( s ^{2} + 4 )}
