Answer:

Step-by-step explanation:
You can do this using the quadratic equation:

Let's first setup our expression:
4x² + 12x = 135
the quadratic formula is:
ax² + bx + c = 0
4x² + 12x - 135 = 0
Then:
a = 4
b = 12
c = -135
Now we plug in our coefficients and solve:

We solve for both to determine the positive one:





So if you are looking for a positive solution, just take the positive one as x.
