Question

Change subject of a formula
Q13.
Make p the subject of the formula y = 3p²-4

Answer 1

`p = \pm\sqrt{(y+4)/(3)`

Step by step explanation:

`~~~~~y = 3p^2 -4\\\\\implies 3p^2 = y+4\\ \\\implies p^2 = (y+4)/(3)\\\\\implies p = \pm\sqrt{(y+4)/(3)`

Answer 2

√y+4÷3=p

Explanation:

y=3p²-4

y+4=3p²

y+4/3=p²

p=√y+4÷3
