WebSolve quadratic equations by factorising, using formulae and completing the square. Each method also provides information about the corresponding quadratic graph. WebSolving by factoring. Suppose we want to solve the equation x^2-3x-10=0 x2 −3x −10 = 0, then all we have to do is factor x^2-3x-10 x2 −3x −10 and solve like before! x^2-3x-10 x2 −3x −10 can be factored as (x+2) (x-5) (x +2)(x −5). [Show me the factorization.] The complete solution of the equation would go as follows:
WebRoots. The "roots" are the solutions to the equation. When the curve crosses the x-axis (y=0) you will have: two solutions. or ONE solution (if it just touches) When the curve does not cross the line there are still solutions, but: the two solutions include Imaginary Numbers.
