expand (3x-x^3)(-7x+pi)+e^9x

expand

(3 x - x^{3}) (- 7 x + π) + e^{9} x

7 x^{4} - π x^{3} - 21 x^{2} + 3 π x + e^{9} x

Solution steps

(3 x - x^{3}) (- 7 x + π) + e^{9} x

Expand

(3 x - x^{3}) (- 7 x + π) : 7 x^{4} - π x^{3} - 21 x^{2} + 3 π x

= 7 x^{4} - π x^{3} - 21 x^{2} + 3 π x + e^{9} x

(6 - x) \cdot (6 + x)

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

\frac{4}{7} + \frac{5}{14}

\frac{( 4 x ^{3} + 7 ) ^{5}}{( 12 x + 9 ) ^{2}}

\frac{z}{( 1 + z ^{3} ) ^{2}}
