Question

What is the value of the algebraic expression `4x^2y-2xy^2+y` if `x=1` and `y=-4`?

Answer 1

`-52`

Explanation:

You can substitute the variables for the number:

`4x^2y = 4* 1^2 * (-4) = -16`

`2xy^2= 2*1*(-4)^2 = 2*16= 32`

`y= -4`

Then you can solve:

`-16-32-4= -52`

Hope this helps!
