Question

Evaluate if x =3 and y = -2 x2+2xy−4y

Answer 1

Answer:

5

Step-by-step explanation:

With the equation $x^2 + 2xy - 4y$, we can substitute the values of x = 3 and y = -2 into the equation to find its result.

$(3^2) + (2\cdot3\cdot-2) - (4\cdot-2)\\\\9 + (6\cdot-2) - (-8)\\9 - 12 + 8\\5$
