Sticky Note
the average of the polynomials 2x2 =5x- 6, 5x2 - 5x- and 30 -7x2 is:
  1. 14
  2. 6
  3. 18
  4. 5x
Explanation

First, we find the sum of the three polynomials, than divide the answer by 3.

Sum of the three polynomials

2x2 + 5x – 6

5x2 – 5x – 6

-7x2 + 30 / 18

Now, Average = Sum of the three polynomials / 3

= 18 / 3 = 6


so. the answer is 6.
