Question

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.

Answer 1

1. If a quadratic has only one real solution, then there has to be a double factor
So in this case
(x-7)(x-7) = 0
expand if needed

2. Question makes no sense.
area cannot be in cubic units
