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.

  • algebra -

    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
