Expand Binomials: Expand the integrand (x−1)(4x−5). To integrate the product of two binomials, we first need to expand the expression. (x−1)(4x−5)=4x2−5x−4x+5=4x2−9x+5
Write Integral: Write the integral with the expanded integrand.Now we can write the integral as:∫(4x2−9x+5)dx
Integrate Separately: Integrate each term separately.The integral of a sum is the sum of the integrals, so we can integrate each term separately.∫4x2dx−∫9xdx+∫5dx
Apply Power Rule: Apply the power rule for integration to each term.The power rule states that ∫xndx=n+1x(n+1)+C, where C is the constant of integration.∫4x2dx=4⋅2+1x(2+1)=34x3∫9xdx=9⋅1+1x(1+1)=29x2∫5dx=5x
Combine Integrated Terms: Combine the integrated terms and add the constant of integration.Now we combine all the integrated terms and add the constant of integration C.34x3−29x2+5x+C
