12-y^2=4-(y-2)^2

Solution

12 - y^{2} = 4 - (y - 2)^{2}

Solution

y = 3

Solution steps

12 - y^{2} = 4 - (y - 2)^{2}

Expand

4 - (y - 2)^{2} : - y^{2} + 4 y

12 - y^{2} = - y^{2} + 4 y

Move

12

to the right side

- y^{2} = - y^{2} + 4 y - 12

Subtract

- y^{2} + 4 y

from both sides

- y^{2} - (- y^{2} + 4 y) = - y^{2} + 4 y - 12 - (- y^{2} + 4 y)

Simplify

- 4 y = - 12

Divide both sides by

- 4

y = 3
