Question

Make y the subject of the formula x=a-2by squared

Answer 1

Answer:

y = ± $\sqrt{\frac{a-x}{2b} }$

Step-by-step explanation:

Given

x = a - 2by² ( subtract a from both sides )

x - a = - 2by² ( multiply through by - 1 to clear the leading negative )

a - x = 2by² ( divide both sides by 2b )

$\frac{a-x}{2b}$ = y² ( take the square root of both sides )

y = ± $\sqrt{\frac{a-x}{2b} }$
