Question

Make y the subject of this formulae X=a-2by^2

Answer 1

`y = \sqrt{(x- a)/(2b)}`

Explanation:

Step 1: Make y the subject of this formula

`x- a = a - a - 2by^(2)`

`(x- a)/(2b) = (2by^(2))/(2b)`

`\sqrt{(x- a)/(2b)} = \sqrt{y^(2)}`

`\sqrt{(x- a)/(2b)} = y`

Answer:
`y = \sqrt{(x- a)/(2b)}`
