...because I'm too dim to do my maths. I'm sure it's simple really but I have:
2x(squared) + 7x - 2 = 0
When you replace x with either -2 or 1/4, the equation is correct but I can't seem to prove this using the quadratic formula or by trying to solve the equation by using brackets. Are there any other ways of proving this?
Any help would be much appreciated.
