Q. Calculate the integral and write the answer in simplest form.∫(−2x2+5)dxAnswer:
Given Integral: We are given the integral to solve:∫(−2x2+5)dxWe will integrate the function term by term.
Integrating −2x2: First, we integrate the term −2x2 with respect to x. The integral of xn with respect to x is n+1x(n+1), so the integral of −2x2 is: ∫(−2x2)dx=−2×∫(x2)dx=−2×2+1x(2+1)=−2×3x3
Integrating 5: Next, we integrate the constant term 5 with respect to x. The integral of a constant a with respect to x is ax, so the integral of 5 is: ∫(5)dx=5x
Combining Integrals: Now, we combine the results of the two integrals and add the constant of integration C. The combined integral is: −2×3x3+5x+C
Final Answer: We simplify the expression by combining like terms, if any. However, in this case, there are no like terms to combine, so the expression is already in its simplest form.The final answer is:−32×x3+5x+C
