Q. Calculate the integral and write the answer in simplest form.∫(−6x−3+2x)dxAnswer:
Identify Integral: Identify the integral to be solved.We need to integrate the function −6x−3+2x with respect to x.
Break Down Integral: Break down the integral into two separate integrals.The integral of a sum of functions is the sum of the integrals of each function, so we can write:\int(\(-6x^{−3} + 2x)\,dx = \int(−6x^{−3})\,dx + \int(2x)\,dx
Integrate First Part: Integrate the first part of the function, −6x−3. The integral of xn with respect to x is (xn+1)/(n+1)+C, where n=−1. Applying this rule: ∫(−6x−3)dx=−6⋅∫(x−3)dx=−6⋅(x−3+1/(−3+1))+C=−6⋅(x−2/(−2))+C=3x−2+C1
Integrate Second Part: Integrate the second part of the function, 2x. Using the same rule as before: ∫(2x)dx=2×∫(x1)dx=2×(1+1x1+1)+C=2×(2x2)+C=x2+C2
Combine Results: Combine the results of the two integrals.The combined result of the integrals is:3x−2+C1+x2+C2Since C1 and C2 are both constants, we can combine them into a single constant C.Final result: 3x−2+x2+C
