Please rearrange h=rx^2-tx to make x the subject.
Ah ok thank you :)
To rearrange the equation h=rx^2-tx to make x the subject, you need to isolate x on one side of the equation.
h = rx^2 - tx
First, let's move all the terms containing x to the left side:
h + tx = rx^2
Now, let's swap the sides of the equation:
rx^2 = h + tx
To solve for x, divide both sides of the equation by r:
x^2 = (h + tx) / r
Finally, take the square root of both sides to undo the square:
x = ±√((h + tx) / r)
Therefore, x is the subject.
it's a quadratic in x:
rx^2-tx-h = 0
use the quadratic formula to find the value(s) of x.
