expand (2y^{2/5}-3x^2)(2y^{2/5}+3x^2)

expand

(2 y^{\frac{2}{5}} - 3 x^{2}) (2 y^{\frac{2}{5}} + 3 x^{2})

4 y^{\frac{4}{5}} - 9 x^{4}

Solution steps

(2 y^{\frac{2}{5}} - 3 x^{2}) (2 y^{\frac{2}{5}} + 3 x^{2})

Apply Difference of Two Squares

(2 y^{\frac{2}{5}} - 3 x^{2}) (2 y^{\frac{2}{5}} + 3 x^{2}) : 4 y^{\frac{4}{5}} - 9 x^{4}

= 4 y^{\frac{4}{5}} - 9 x^{4}

(x - 2 + 2) (x - 2 - 2)

(2 x + \frac{1}{x ^{2}})^{6}

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

(x + 2) (x - 3)

53 (22 + 4)
