Question

Please help me do this maths calculation ​

Answer 1

x=y^2-4y+12 is the required answer

Answer 2

x =
`y^(2)` - 4y + 12

Explanation:

y = 2 +
`√(x-8)`

Put the 2 on the other side

y - 2 =
`√(x-8)`

Square both sides

`(y-2)^(2)` = x - 8

Expand the brackets

`y^(2)` - 4y + 4 = x-8

Move 8 to the other side

x =
`y^(2)` - 4y + 12
