Question

How do you solve this problem ??

Answer 1

`x=3c√(a) -b^2`

Explanation:

`√(a) =(x+b^2)/(3c)`

Multiply both sides by 3c:

`\implies √(a) \cdot 3c=((x+b^2) \cdot 3c)/(3c)`

`\implies 3c√(a) =x+b^2`

Subtract
`b^2` from both sides:

`\implies 3c√(a) -b^2=x+b^2-b^2`

`\implies 3c√(a)-b^2=x`

Switch sides:

`\implies x=3c√(a) -b^2`
