Question

The largest solution of x2−x=6 is

Answer 1

If x2 is x squared then yes the quadratic equation would have multiple solutions. (2)

First subtract both sides by 6
x^2 - x - 6 = 0
Then, factor
(x + 2)(x - 3)= 0
The solutions for x would be either -2, or 3. 
Final answer: the largest solution of x^2 - x= 6 is x=3

Answer 2

The left side of the equation subtracts x from 2x. 
That means 1x, or just simply x, is left on the left side. 
We now have this:   x = 6 
So, x is 6. Hope this helps!
