c is the constant. Since 2x^2 - x = 3 can rewrite as : 2x^2 - 1x - 3 = 0 So the coefficients of this equation is a=2 for x^2 b= - 1 for x c= - 3 is the constant. To slove it We have to plug in the coefficients a=2 b= -1 c= -3 to x = (-b ...
This quadratic equation only has a single solution, at x = -2/3. Notice that this will be the case anytime the value under the square root in the formula is zero. The value under the square root in the quadratic formula, b2−4ac, has a unique name. It is called the discriminant....
