How many solutions exist for a quadratic equation? How do we determine whether the solutions are real or complex?
Translate the following into a quadratic equation, and solve it: The length of a rectangular garden is four times its width; if the area of the garden is 196 square meters, what are its dimensions?
You can put this solution on YOUR website! D=discriminant =
if D>0 2 reals
if D=0 1 real
if D<0 2 complex roots
let L be the length and W width A=area
take L's value from eq 2 and A's value from eq 3 and plug them into eq 1
