expand 1+(e^x+3x^2)^2

expand

1 + (e^{x} + 3 x^{2})^{2}

1 + e^{2 x} + 6 e^{x} x^{2} + 9 x^{4}

Solution steps

1 + (e^{x} + 3 x^{2})^{2}

(e^{x} + 3 x^{2})^{2} : e^{2 x} + 6 e^{x} x^{2} + 9 x^{4}

= 1 + e^{2 x} + 6 e^{x} x^{2} + 9 x^{4}

- \frac{24 x ^{2}}{( x ^{3} - 8 ) ^{2}}

e^{x} (x e^{- x} + 1)

y^{'} (x) (x + y - 2)^{2}

\frac{36 ( 7 x - y ) ( x + 7 y )}{25}

\frac{3}{2 ( 2 t - 1 )}
