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.
