Question 483300: Quadratic equations, which are expressed in the form of ax2 + bx + c = 0, where a does not equal 0, may have how many solutions? Explain why?
Think of a linear equation. How many solutions may that have?
Can you extend this to a an n-degree equation?
You can put this solution on YOUR website! Quadratic equations have two solutions. If you want to learn why, look up the proof of the fundamental theorem of algebra (most are quite advanced and use some complex analysis).
