Question

Make q the subject of the formula p = 2q2 .​

Answer 1

q = ±
`\sqrt{(p)/(2) }`

Explanation:

Given

p = 2q² ( divide both sides by 2 )

`(p)/(2)` = q² ( take the square root of both sides )

±
`(p)/(2)` = q

Answer 2

q = +√p/2

Explanation:

p = 2q²

divide both sides by 2 and root we get,

√p/2 = √2q²/2

√p/2 = q

q = +√p/2

Thus, q = +√p/2
