Find lim PLEASE I NEED HELP ASAP

Computing the limit directly:

Alternatively, you can recognize the limit as being equivalent the derivative of f(x) at x = 2, in which case differentiating and plugging in 2 gives

f'(x) = 2x + 1   =>   f' (2) = 5

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.
