Question

6m^2-3mn+2m-n/6m^2+3mn+2m+n, ввчислите её значения при n/m=4

Answer 1

Ответ:

Пошаговое объяснение:

$>\ n=4m\\\\\\\frac{2m-4m}{2m+4m} =\frac{-2m}{6m} =-\frac{1}{3}$

Answer 2

To evaluate the given expression, we'll substitute the value of n/m with 4 and simplify the expression.

Given expression: (6m^2 - 3mn + 2m - n) / (6m^2 + 3mn + 2m + n)

Substituting n/m with 4, we have:

(6m^2 - 3(4m) + 2m - 4m) / (6m^2 + 3(4m) + 2m + 4m)

Simplifying further:

(6m^2 - 12m + 2m - 4m) / (6m^2 + 12m + 2m + 4m)

(6m^2 - 14m) / (6m^2 + 18m)

Factoring out a common factor of 2m from the numerator and denominator:

2m(3m - 7) / 6m(m + 3)

So, the simplified expression with n/m = 4 is:

(2m(3m - 7)) / (6m(m + 3))

Please note that we have simplified the expression, but we cannot determine its numerical value without a specific value for 'm.' If you provide a specific value for 'm,' I can calculate the expression's value for that particular value of 'm.'
