the sum of zeros of the polynomial 3x2+3x-18
Answers
Answer:
-1
Step-by-step explanation:
3x2+3x-18
Sum of zeroes=-b/a
α+β=-b/a
put values in given formula,we get
α+β=-3/3
= -1
Hence, the sum of zeroes is -1.
The sum of zeros of the polynomial 3x² + 3x - 18 is - 1
Given :
The polynomial 3x² + 3x - 18
To find :
The sum of zeros of the polynomial 3x² + 3x - 18
Concept :
Then ,
Solution :
Step 1 of 2 :
Write down the given polynomial
Here the given polynomial is 3x² + 3x - 18
Step 2 of 2 :
Find Sum of the zeroes
The given polynomial is 3x² + 3x - 18
Now comparing with the general polynomial ax² + bx + c we get a = 3 , b = 3 , c = - 18
Hence the sum of the zeroes of the polynomial
