Answer:
19/18
Step-by-step explanation:
substitute the value of m(11/6) in m-7/9
which is equal to 11/6 -7/9 =19/18
The subtraction in the standard form of the polynomial is
.
Given that
Expression;
.
We have to determine
The subtraction of a polynomial.
According to the question
Expression;
.
To find the subtraction of the polynomial follow all the steps given below.
- Step1; Write the expression as an additive inverse.

- Step2; Rewrite terms that are subtracted as the addition of the opposite.

![\rm 6m^5 + 3 + (-m^3) + (-4m) + m^5 + (2m^3) + 4m + (-6)\\\\(6m^5 + m^5) + [3 + (-6)] + [(-m^3) + (-2m^3)] + [(-4m) + 4m]\\\\](https://tex.z-dn.net/?f=%5Crm%206m%5E5%20%2B%203%20%2B%20%28-m%5E3%29%20%2B%20%28-4m%29%20%2B%20m%5E5%20%2B%20%282m%5E3%29%20%2B%204m%20%2B%20%28-6%29%5C%5C%5C%5C%286m%5E5%20%2B%20m%5E5%29%20%2B%20%5B3%20%2B%20%28-6%29%5D%20%2B%20%5B%28-m%5E3%29%20%2B%20%28-2m%5E3%29%5D%20%2B%20%5B%28-4m%29%20%2B%204m%5D%5C%5C%5C%5C)
- Step4; the resulting polynomial in standard form is,
![\rm (6m^5 + m^5) + [3 + (-6)] + [(-m^3) + (-2m^3)] + [(-4m) + 4m]\\\\ 7m^5-3m^2-3](https://tex.z-dn.net/?f=%5Crm%20%286m%5E5%20%2B%20m%5E5%29%20%2B%20%5B3%20%2B%20%28-6%29%5D%20%2B%20%5B%28-m%5E3%29%20%2B%20%28-2m%5E3%29%5D%20%2B%20%5B%28-4m%29%20%2B%204m%5D%5C%5C%5C%5C%207m%5E5-3m%5E2-3)
Hence, the subtraction in the standard form of the polynomial is

Always try putting x=1 and x=-1 to see if we can find a zero.
If x=1 we get 5+8+1-2 which is not zero.
If we change the signs of the odd powers of x we get -5+8-1-2 which is zero so x=-1 is a zero and x+1 must therefore be a factor. Now we can use synthetic division to find the quadratic:
-1 | 5 8 1 -2
5 -5 -3 2
————
5 3 -2 | 0 = 5x²+3x-2 = (5x-2)(x+1).
Therefore the real zeroes are -1, 2/5, since -1 is a duplicate zero (because the cubic factorises into (5x-2)(x+1)²).
