1.Write a quadratic equation in the variable x having the given numbers as solutions. Type the equation in stadard form ax^2+bx+c=0
Solution 7, only solution
2.The width of a rectangle is less than the length. The area is 4ft^3. Find the length and the width.

1. If a quadratic has only one real solution, then there has to be a double factor
So in this case
(x7)(x7) = 0
expand if needed
2. Question makes no sense.
area cannot be in cubic units
