For the answer to the question above asking <span>Melissa is helping her dad build a walkway in their backyard. The walkway will be 545454 feet long and 1.51.51, point, 5 feet wide. The local hardware store sells tiles which are 1.51.51, point, 5 by 1.51.51, point, 5 feet and come in boxes of 121212.</span>
54 dived by 1.5 is 36.
36 dived by 12 is 3.
You need 3 boxes.
What you must do in this case is to find the roots of the polynomial.
We have then:
x ^ 2 + 20x + 100 = 36
Rewriting:
x ^ 2 + 20x + 64 = 0
The values of the roots are:
x1 = -4
x2 = -16
Remember that the values of the roots are what make the polinome zero
Answer:
x1 = -4
x2 = -16
