What is the solution to a quadratic equation?
There are 2 (main) ways you can find the solution to a quadratic equation: Factorisation: If you take, for example, the equation (x-3)(x-2) = 0. Either (x-3) or (x-2) must equal 0 for the equation to...

What does it mean if the quadratic equation has no solution?
Generally, when we say a quadratic equation has no solutions, it means that the graph does not cross the x-axis at all. In other words, it means that there are no values for x when y equals 0...

Do all quadratic equation have a solution?
No. Some have two solutions where as some have none.

Why are there two solutions to quadratic equations?
In theory, a quadratic equation can be separated into two factors. For example, in the equation x2 - 5x + 6 = 0, the left part can be factored as (x-3)(x-2) = 0. For the product to be zero, any of...

Why do quadratic equations have to solutions?
Because all positive numbers have 2 square roots, eg 9 = 3 x 3 and also -3 x -3
