Make y the subject of the formula x=a-2by²

Answer 1

Answer:

y = ± $\sqrt{\frac{a-x}{2b} }$

Step-by-step explanation:

Given

x = a - 2by² ( add 2by² to both sides )

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

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

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

y = ± $\sqrt{\frac{a-x}{2b} }$

Answer 2

Answer:

$y = a - x \di2b$

Step-by-step explanation:

$2b {y }^{2} = a - x$

$2b {y}^{2} \div 2b = a - x \ \div 2b$

${y}^{2} = a - x \div 2b$

$y = \sqrt{a - x \div 2b}$
