expand e^{-x10}(1+x*10)-0.2

expand

e^{- x \cdot 10} \cdot (1 + x \cdot 10) - 0.2

e^{- 10 x} + 10 e^{- 10 x} x - 0.2

Solution steps

e^{- x \cdot 10} (1 + x \cdot 10) - 0.2

= e^{- 10 x} (1 + 10 x) - 0.2

Expand

e^{- x \cdot 10} (1 + x \cdot 10) : e^{- 10 x} + 10 e^{- 10 x} x

= e^{- 10 x} + 10 e^{- 10 x} x - 0.2

\frac{x \cdot ( 1 - x ) ( 20 + 3 \cdot x ) ^{3}}{( F ^{3} + 9 \cdot a ^{3} \cdot x ^{3} )}

y cos (x + y) d x + (sin (x + y) + y cos (x + y)) d y

- \frac{( e - x ) ^{2}}{4 k t} + e + e^{2}

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

\frac{7 x + 12}{x ( x + 2 )}
