Answer
$44$
Work Step by Step
$$x^{2}-4(x-y)$$
for $x=8$ and $y=3$
substitute 8 for each x and 3 for each y $$8^{2}-4(8-3)$$ complete grouped operations first $8^{2}-4(5)$ next are exponents $$64-4(5)$$ Then multiplication or division in order left to right $$64-20$$ finally addition or subtraction in order left to right $$44$$
