$\displaystyle \tt \int9 {x}^{2} + 7x \: dx$

$\tt = \cfrac{9 {x}^{2 + 1} }{2 + 1} + \dfrac{ {7x}^{1 + 1} }{1 + 1} + C$

$\tt = \cfrac{9 {x}^{3} }{3} + \dfrac{ {7x}^{2} }{2} + C$

$\tt = \cfrac{9 }{3} {x}^{3} + \dfrac{ {7}}{2} {x}^{2} + C$

$\boxed{\tt = 3{x}^{3} + \dfrac{ {7}}{2} {x}^{2} + C}$

Penjelasan dengan langkah-langkah:

Integral ( 9x² + 7x ) dx

= 9 x²+¹ + 7 x¹+¹ + C

2+1 1+1

= (9/3)x³ + (7/2)x² + C

= 3x³ + 3½x² + C
