Question

Lots of point up for grabs

Answer 1

Minus a from both sides
x-a=-2by²
times both sides by -1
a-x=2by²
divide both sides by 2b
$\frac{a-x}{2b}=y^2$
sqrt both sides
$y= \sqrt{\frac{a-x}{2b}}$

Answer 2

Answer:

minus a from both sides

x-a=-2by²

times both sides by -1

a-x=2by²

divide both sides by 2b

sqrt both sides
