Standard form of polynomial = ax² + bx + c
Zeros: x = {-2,3}
This gives the factors as, (x + 2) (x - 3)
On expanding this:
(x + 2) (x - 3)
x(x - 3) + 2(x - 3)
x² - 3x + 2x - 3
x² - x - 3
Polynomial = <em>x² - x - 3</em>
2x = 3
x = 3/2 or 1 1/2 or 1.5
Answer:
21, 17, 13
Step-by-step explanation:
Find the mean of the 2 given values
mean = = = 17
Noe find the mean of 25 and 17 and 17 and 9
mean = = = 21 and
mean = = = 13
Thus the 3 means are 21, 17 and 13, that is
25, 21, 17, 13, 9
