Q. Calculate the integral and write the answer in simplest form.∫(x−2−4x3)dxAnswer:
Integrate each term separately: We are given the integral of the function x−2−4x3. We will integrate each term separately.The integral of x−2 is −x−1 or −x1, and the integral of −4x3 is −44x4 or −x4.So, the integral of the given function is:∫(x−2−4x3)dx=∫x−2dx−∫4x3dx
Integrate x−2: Now we will integrate each term separately.For the first term:∫x−2dx=∫x−2+1/(−2+1)dx=−x−1+C1For the second term:∫4x3dx=4∫x3dx=4(x3+1/(3+1))=x4+C2
Integrate −4x3: Combining the two integrals, we get:∫(x−2−4x3)dx=−x−1−x4+CWhere C is the constant of integration, which is a combination of C1 and C2.
Combine the integrals: We can simplify the expression by combining the constants of integration into a single constant, which we will also call C. So the final answer is: ∫(x−2−4x3)dx=−x1−x4+C
