Answer:


\boxed{\boxed{\Large\text{$21$}}}\\

Explanation:

To evaluate the expression:


\boxed{\Large\text{$4(a+b)^2+4a-3b$}}

We are given that a = 2, and b = -3. Therefore we can plug in these values:


\Large\text{$\implies 4\big((2)+(-3)\big)^2+4(2)-3(-3)$}

And now we can solve this:


\Large\text{$\implies 4\big(-1\big)^2+8+9$}\\\\\Large\text{$\implies 4+8+9$}\\\\\boxed{\boxed{\Large\text{$\implies 21$}}}\\
