Q. Calculate the integral and write the answer in simplest form.∫(5x−2−2)dxAnswer:
Identify Integral: Identify the integral to be solved.We need to find the indefinite integral of the function 5x−2−2 with respect to x.The integral is written as ∫(5x−2−2)dx.
Break Down: Break down the integral into simpler parts.The integral of a sum is the sum of the integrals, so we can write:∫(5x−2−2)dx=∫5x−2dx−∫2dx.
Integrate Separately: Integrate each term separately.For the first term, ∫5x−2dx, we use the power rule of integration, which states that ∫xndx=n+1xn+1+C, where n=−1.Applying the power rule, we get:∫5x−2dx=5×∫x−2dx=5×(−x−1)+C1=−x5+C1, where C1 is a constant of integration.
Integrate Second Term: Integrate the second term.For the second term, ∫2dx, the integral of a constant is the constant times the variable of integration plus another constant of integration.So, ∫2dx=2x+C2, where C2 is another constant of integration.
Combine Results: Combine the results of the two integrals.Combining the results from Step 3 and Step 4, we get:∫(5x−2−2)dx=−x5+2x+C1+C2.Since C1 and C2 are arbitrary constants, we can combine them into a single constant, C.Therefore, the integral is:∫(5x−2−2)dx=−x5+2x+C.
