Question

Evaluate if x =3 and y = -2

x2+2xy−4y

Answer 1

5

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`

Hope this helped!
