Step 1: Recognize that the problem involves finding the indefinite integral of the function 5x^2 + 25 with respect to x. Recall that the indefinite integral of a function f(x) is the antiderivative of f(x), plus a constant of integration C.
Step 2: Break the integral into two separate terms: ∫(5x^2)dx + ∫(25)dx. This allows us to integrate each term individually.
Step 3: For the first term, ∫(5x^2)dx, use the power rule for integration: ∫(ax^n)dx = (a/(n+1))x^(n+1) + C. Here, a = 5 and n = 2, so the antiderivative becomes (5/3)x^3.
Step 4: For the second term, ∫(25)dx, recall that the integral of a constant is the constant multiplied by x. Thus, the antiderivative of 25 is 25x.
Step 5: Combine the results from Step 3 and Step 4 to write the final expression for the indefinite integral: (5/3)x^3 + 25x + C, where C is the constant of integration.
