For example, 12x2 + 11x + 2 = 7 12 x 2 + 11 x + 2 = 7 must first be changed to 12x2 + 11x + −5 = 0 12 x 2 + 11 x + − 5 = 0 by subtracting 7 from both sides. Example.Any quadratic of the form ax^2 + bx + c can be solved using the formula ( -b +/- sqrt (D) )/2a with D= b^2-4*a*c. However, if D is less than zero it cannot be solved regularly. This requires the introduction if the imaginary number i = sqrt (-1). I think this allows us to factor all quadratics. So short answer: yes.

So applying the quadratic formula right here, we get our solutions to be x is equal to negative b. b is 10. So negative b is negative 10 plus or minus the square root of b squared. b is 10. So b squared is 100 minus 4 times a times c. So minus 4 times negative 3 times negative 3. Let me just write it down.
