Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Algebra Calculator shows you the step-by-step solutions! Solves algebra problems and walks you through them. When solving equations, knowing that 3x is the same as saying three equal groups of something, makes it easy to come to the conclusion that dividing whatever 3x equals into 3 equal groups will... If you mean: (3x-1) (x+1) = 0, then it is 3x squared+2x-1 = 0. Its solutions are: x = 1/3 or x = -1.
