Exercise

$\lim_{x\to0}\left(\left(2x+4\right)^2-16\right)$

Step-by-step Solution

1

Evaluate the limit $\lim_{x\to0}\left(\left(2x+4\right)^2-16\right)$ by replacing all occurrences of $x$ by $0$

$\left(2\cdot 0+4\right)^2-16$
2

Multiply $2$ times $0$

$\left(0+4\right)^2-16$
3

Add the values $0$ and $4$

$4^2-16$
4

Calculate the power $4^2$

$16-16$
5

Subtract the values $16$ and $-16$
