Take your equation and multiply each side by R to get rid of frcations.
This will give you 1 + R^2 = 3R + 7.
Move everything over to the left to get: R^2 - 3R - 6= 0.
So a=1, b=-3, c=-6.
Then use the quadratic formula!
I need help with this equation. It is a hidden equation which I have tried to solve on my maths booklet.
The steps that must be followed are:
ax^2 + bx + c = 0
I have to use the quadratic formula and tranpose the above
here is my question
1 / R + R = 3 + 7 / R
I need to get the A , b , c and plug it in the quadratic formula but the issue is i don't get the right answer which is 4.37, I believe I get the wrong A , B , C values at the start.
If i need to be more specify please tell me.
