Answer:
6/7-61/1
Step-by-step explanation:
2 - 2y^2 - x/y
2x^2/x^2 = 2
and
x^2/xy = x/y
therefore
2x^2/x^2 - y^2 - x^2/xy - y^2
= 2 - y^2 - x/y - y^2
= 2 - y^2 - y^2 - x/y
= 2 - 2y^2 - x/y
4p+9=
(first start with multiple or division division from right to left then with addition from right to left)
4*4+9=
16+9=25
