Evaluate the integral. / 12x11 + 2x dx dx. Use the Logarithmic Formula for integrals. Step 1 Notice that the numerator is the derivative of the denominator. Thus the integral is of the form du = Inul + C dx = 1 d u dx. 12 Let u=x +x and du = 12 (12x11 + 2x) dx. Substitute these values to write the integral in terms of u and du. 12x11 + 2x 12x11 + 2x dx = x12 + x In (x12 + x) C du 0 u Step 2 Next, we perform the integration with respect to u. Remember the constant of integration. Remember to use In(lul) where appropriate. U Submit Skip (you cannot come back)
