Question

c. integration of(2x - 5x + 7)dx
​

Answer 1

Answer:

$= > {x}^{2} - \frac{5}{2} {x}^{2} + 7x + c \:$

Step-by-step explanation:

$= > \int(2x - 5x + 7)dx \\ \\ = > 2\int \: x.dx - 5 \int \: x.dx + 7 \int(1)dx \\ \\ = > 2 \times \frac{ {x}^{1 + 1} }{1 + 1} - 5 \times \frac{ {x}^{1 + 1} }{1 + 1} + 7 \times x + c \\ \\ = > 2 \times \frac{ {x}^{2} }{2} - 5 \times \frac{ {x}^{2} }{2} + 7x + c \\ \\ = > {x}^{2} - \frac{5}{2} {x}^{2} + 7x + c$
