A quadratic equation must be able to be written in the form:
y = ax2 + bx + c where a is not equal to zero. The graph will be a parabola. There must be a "squared" term and no larger exponent than...
A linear equation, when graphed, is always a line. A quadratic is a curve. Also, linear equations are of the form y=mx+b where m and b are arbitrary constants and quadratics are y=(x^2) +mx +b where...
There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.
Using "^" for powers. A quadratic equation has a term like x squared (or whatever variable you are using squared). For example, 5x^2 + 3x - 7 = 0. The general form is ax^2 + bx + c = 0.
A linear...
