Using the quadratic equation formula: x = -5-/+ the square root of 7

x^2-3x-28=0...................

How about finding the solutions of the quadratic equation: x^2-14x+49 = 0

4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.

52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
