{ \bold{ \mathscr{\boxed{INTEGRATION}}}}

{\rm \bold{\int(x + 3)(2 - x)}} \: dx \\  \\  \implies \int2x - x {}^{2} + 6 - 3x \:  \:  dx\\ \\   \implies \int \: 6 - x { - x \: }^{2} \:  dx

[ Multiplying the terms ]

→ Now , separating the integral we get

 \int6 \:  \: dx \:  \:   -  \int \: x \:  \: dx \:  -  \int \: x {}^{2}  \: dx \\  \\ \implies6x \:  -  \frac{x {}^{1 + 1} }{1 + 1}  -  \frac{x {}^{2 + 1} }{2 + 1}  + c\\   \:  \\  \implies \: 6x \:  -  \dfrac{{x}^{2} }{2}  -  \frac{x {}^{3} }{3}  + c

So the solution of the given integral is

 \huge\int( x + 3)(2 - x) \:  = 6x -  \frac{x {}^{2} }{2}   -   \frac{x {}^{3} }{3}  + c

Where C is any Arbitrary Constant .
