$$30$$
To evaluate this expression, we substitute $-2$ where we see $x$ and $3$ where we see $y$: $$4(-2)^2(3) + 5(-2)(3) - 6(-2)$$ Evaluate the exponent first: $$4(4)(3) + 5(-2)(3) - 6(-2)$$ Multiply to simplify: $$16(3) + 5(-6) + 12$$ $$48 - 30 + 12$$ Subtract first, according to order of operations: $$18 + 12$$ Add to evaluate the expression: $$30$$
