expand (1+x^{4/3})(1-x^{2/3})

expand

(1 + x^{\frac{4}{3}}) (1 - x^{\frac{2}{3}})

1 - x^{\frac{2}{3}} + x^{\frac{4}{3}} - x^{2}

Solution steps

(1 + x^{\frac{4}{3}}) (1 - x^{\frac{2}{3}})

Apply FOIL method

(1 + x^{\frac{4}{3}}) (1 - x^{\frac{2}{3}}) : 1 - x^{\frac{2}{3}} + x^{\frac{4}{3}} - x^{2}

= 1 - x^{\frac{2}{3}} + x^{\frac{4}{3}} - x^{2}

(2 t - 1) (t^{4} + t) + sin (π t) (2 t - 1)^{2}

\frac{x ^{2} + 4}{( x + 2 ) ^{2}}

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

(2 + i)^{6}

sin (t) cos (10 (t - r))
