What is the quadratic formula of 6x-5 equals 2x?

Answer 1

6x - 5 = 2x

That's a linear equation, and never comes anywhere near anything quadratic.

There's only one value of 'x' that makes it a true statement, which you can find like this:

Add 5 to each side:

6x = 2x + 5

Subtract 2x from each side:

4x = 5

Divide each side by 4:

x = 1.25
