Let u = x², then we would have u² + 5u - 6 = 0
From here, we can factor it and get us (u-1) (u+6) = 0
So our solution for u is u = - 6 or 1.
Now substitute u back to x².
x² = - 6 or 1
x = ±√ (-6) or ±√1
Since ±√ (-6) is not real number, we ignore it.
Which leave us x = ±√1 = ±1
So our real solution is x = - 1 or 1.
