Answer:
a = 3
Step-by-step explanation:
Factor both expressions
x² - x - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)
The factors are - 3 and + 2 , since
- 3 × 2 = - 6 and - 3 + 2 = - 1 , thus
x² - x - 6 = (x - 3)(x + 2)
-----------------------------------
x² + 3x - 18
consider factors of constant term (- 18) which sum to give the coefficient of the x- term (+ 3)
The factors are + 6 and - 3 , since
6 × - 3 = - 18 and 6 - 3 = + 3 , thus
x² + 3x - 18 = (x + 6)(x - 3)
Both expressions have a common factor of (x - 3)
Compare with (x - a ), then a = 3
The degree of the polynomial will tell you the max amount of zeros you will have. 11 in this case.
However you can also have 9,7,5,3,1 (keep subtracting by 2)
So the answer is 1.

Answer:

Step-by-step explanation:
![\frac{3}{5}[50] = \frac{150}{5} = 30](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D%5B50%5D%20%3D%20%5Cfrac%7B150%7D%7B5%7D%20%3D%2030)
The fraction ⅗ is equivalent to 60%, so just take three-fifths of 50 to get 30.
