Question 199506: 1) what type of solution do you get for a quadratic equation where D<0? give the reasons for your answer. Also provide an example of such a quadratic equation and find the solution of the equation.
2) create a real-life situation that fits into the equation(x+3)(x-5)=0 and express the situation as the same equation. Answer by solver91311(24713) (Show Source):
One real root with a multiplicity of two. That is to say that the trinomial is a perfect square and has two identical factors.
A conjugate pair of complex roots of the form where is the imaginary number defined by
Say you want to build a box to store your note cards. All you know is that your note cards are 2 inches longer than they are wide and the area of the cards is 15 square inches. What is the minimum dimensions for the inside of the box if you want to store no more than a 4 inch tall stack of note cards?
Let represent the length. Then is the width. The area is the length times the width, so:
