How to solve for x cubic function
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: WebHow to discover for yourself the solution of the cubic .
