Find the number and type of solutions for: 3x2 � 10x + 3 = 0.
----
Use ^ (Shift 6) for exponents.
3x^2 � 10x + 3 = 0
----------
It's a quadratic, 2nd order. All quadratics have 2 solutions.

If the question in fact only asks for the number and type of solutions, then all you need to do is look at the discriminant, b^2-4ac.

The discriminant is positive; there are 2 real solutions.

Note the discriminant is a perfect square; that means the equation can be solved by factoring. Many students go straight to the quadratic formula every time for solving quadratic equations; however, with a little practice solving by factoring is faster.
