Rewrite Integral: Rewrite the integral to clarify the expression: ∫(4x3+6)dx.
Separate Parts: Separate the integral into two parts: ∫4x3dx+∫6dx.
Integrate Constant: Integrate the constant: ∫6dx=6x+C, where C is the constant of integration.
Substitution for Integral: The integral of 4x3 is not a standard integral. We need to use substitution. Let u=x3, then du=3x2dx.
Correction of Substitution: We made a mistake in the previous step. We need to correct the substitution. Let u=x3, then du=3x2dx is incorrect because we don't have x2 in our integral. We cannot integrate 4x3 using elementary functions.
