expand (2x^5+3y^4)(-4x^2+9y^4)

expand

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

- 8 x^{7} + 18 x^{5} y^{4} - 12 y^{4} x^{2} + 27 y^{8}

Solution steps

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

Apply FOIL method

(2 x^{5} + 3 y^{4}) (- 4 x^{2} + 9 y^{4}) : - 8 x^{7} + 18 x^{5} y^{4} - 12 y^{4} x^{2} + 27 y^{8}

= - 8 x^{7} + 18 x^{5} y^{4} - 12 y^{4} x^{2} + 27 y^{8}

x^{4} - y^{2} + 2 x^{2} + 1

\frac{( 3 x ^{4} - 6 x ^{3} + 19 x - 10 - 7 x ^{2} )}{( x - 2 )}

(3 b + 2 a)^{2}

(\frac{9 m ^{4} n ^{10}}{- 3 m ^{2} n ^{5}})^{- 1}

\frac{2 ^{12}}{2 ^{8}}
