$- 52$ $-52$

You can substitute the variables for the number:

$4 x^{2} y = 4 \cdot 1^{2} \cdot (- 4) = - 16$ $4x^2y = 4* 1^2 * (-4) = -16$

$2 x y^{2} = 2 \cdot 1 \cdot {(- 4)}^{2} = 2 \cdot 16 = 32$ $2xy^2= 2*1*(-4)^2 = 2*16= 32$

$y = - 4$ $y= -4$

Then you can solve:

$- 16 - 32 - 4 = - 52$ $-16-32-4= -52$

Hope this helps!
