please help this is a simple rearranging formula question but i keep getting it wrong

Answer:
Answer is given below with explanations.
Step-by-step explanation:
[tex]y = 2a - b {x}^{2} \\ we \: want \: to \: make \: x \: as \: subject \\ y = 2a - b {x}^{2} \\ sutract \:2 a \: on \: both \: sides \\ y - 2a = - b {x}^{2} \\ multipy \: minus \: sign \\ 2a - y = b {x}^{2} \\ divide \: by \: b \\ \frac{2a - y}{ b } = {x}^{2} \\ x = \sqrt{ \frac{2a - y}{b} } [/tex]
HAVE A NICE DAY!
