Most devices should have Google Play Store app pre-installed (Android 2.2 or newer). However, if the HCL Me Y2 doesn't have it, it is possible to still install the Google Play Store. As with any modifications, keep in mind that this might void any warranty you may have.
You will need to turn off the security settings to allow the install to take place (Settings > Security > Unknown sources...check the box). Next, download the Google Play Store apk, courtesy of the Android Police site (see Related Links). Once the apk is downloaded, from your notification dropdown tap on the file to install.
y2 + y2 = 2y2
y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2
y2
4x-y2 = 2
88 + 5y - y2 66 - 3y + y2 Subtract: 22 + 8y -2y2
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2
It is: y2

y2 there will me many solutions
4 - y2 can be written as 22 - y2. This has become of the form of x2 - y2.Expansion for x2 - y2 is (x+y)(x-y).So, 4 - y2 = 22 - y2 = (2+y)(2-y)
x2 + y2 =x2 + y2 = 5x2 + y2 = 10x2 + y2 = 25
There is no expansion for x2 + y2
