A real solution is a solution to something like a quadratic equation involving only real numbers, not imaginary or complex numbers. A distinct solution, in the example of a quadratic, is where the curve crosses the X axis in two separate, distinct places.

How To Know If An Equation Has A Real Solution

Frequently, in Algebra class, you will be called to find all "real solutions" of an equation. Such questions essentially are asking you to find all solutions of an equation, and should any imaginary solutions (containing the imaginary number 'i') come up, to discard these solutions.

  • For the quadratic equation ax2 + bx + c = 0, the discriminant is D = The discriminant tells us how many real solutions a quadratic equation has. If D > 0, the equation has___ real solution(s). If D = 0, the equation has___ real solution(s). If D < 0, the equation has___ real solution(s). Expert Answer . This problem has been solved! See the answer. Previous question Next question .
