x^3-7 x+6 x^2+3 x ~d x=
Options
- Ax^2 2 +3 x- |x|+ c , where c is a constant of integration.
- Bx^2 2 +3 x+2 |x|+ c , where c is a constant of integration.
- Cx^2 2 -3 x+2 |x|+ c , where c is a constant of integration.
- Dx^2 2 -3 x- |x|+ c , where c is a constant of integration.
Correct answer
C. x^2 2 -3 x+2 |x|+ c , where c is a constant of integration.
Step-by-step solution
aligned Let I & = x^3-7 x+6 x^2+3 x & = (x-3+ 2 x+6 x^2+3 x ) d x & = (x-3+ 2(x+3) x(x+3) ) d x & = (x-3+ 2 x ) d x & = x^2 2 -3 x+2 |x|+ c aligned
