Q. Calculate the integral and write the answer in simplest form.∫(6x−3−5x4)dxAnswer:
Identify Integral: Identify the integral to be solved.We need to find the indefinite integral of the function 6x−3−5x4 with respect to x.
Apply Power Rule: Apply the power rule for integration to each term separately.The power rule for integration states that ∫xndx=(n+1)x(n+1)+C, where n=−1.For the first term, 6x−3, we add 1 to the exponent and divide by the new exponent.For the second term, −5x4, we also add 1 to the exponent and divide by the new exponent.
Integrate 6x−3: Integrate the first term, 6x−3.∫6x−3dx=6×∫x−3dx=6×−3+1x−3+1=6×−2x−2=−3x−2+C1
Integrate −5x4: Integrate the second term, −5x4.∫−5x4dx=−5×∫x4dx=−5×4+1x4+1=−5×5x5=−x5+C2
Combine Integrals: Combine the results of the two integrals.Since the integral of a sum is the sum of the integrals, we add the results from Step 3 and Step 4.−3x−2−x5+C1+C2We can combine the constants C1 and C2 into a single constant C because the sum of two arbitrary constants is also an arbitrary constant.−3x−2−x5+C
Write Final Answer: Write the final answer in simplest form.The simplest form of the integral is −3x−2−x5+C.
