When a takes any number that Na + 3 is not equal to 0, the value of formula (na-2) / (Na + 3) is a fixed value, where M-N = 6, find the value of M, n

When a takes any number that Na + 3 is not equal to 0, the value of formula (na-2) / (Na + 3) is a fixed value, where M-N = 6, find the value of M, n

A:
Because the ratio is constant, the numerator and denominator are proportional
There are - 2K = 3, k = - 3 / 2
So - 3m / 2 = n
And M-N = 6
The solution is m = 12 / 5, n = - 18 / 5

When a takes any number that conforms to Na + 3 ≠ 0, the value of formula (MA-2) / (Na + 3) is a fixed value, where M-N = 6, find m, N,

(MA-2) / (Na + 3) = ((n + 6) A-2) / (Na + 3) = (Na + 6a-2) / (Na + 3) = (Na + 3 + 6a-5) / (Na + 3) = 1 + (6a-5) / (Na + 3) (6a-5) / (Na + 3) is a definite value. Let = k6a-5 = KNA + 3K = - 5K = - 5 / 36a = - 5 / 3 * Nan = - 18 / 5m = 12 / 5

If (a + m) (A-2) = a ^ 2 + na-6 holds for any value of a, find the value of M, n
=Answer me

（a+m）（a-2）
=A ^ 2 + (m-2) a-2m = a ^ 2 + na-6 holds for any value of A
(m-2)=n
2m=6
m=3
n=1

If the value of the square plus ax minus y plus 6 minus 2bx plus 3x plus 5Y plus 1 of the algebraic formula 2x has nothing to do with the value of the letter X, find the flat of the algebraic formula 5A
Square minus (the bisection of 2A minus (the bisection of 2A minus the bisection of AB)

The square of 2x + ax-y + 6-2bx + 3x + 5Y + 1 has nothing to do with the value of the letter X,
So the square of 2x + ax-2bx + 3x = 0, a = - 2, B = 3 / 2
Just take in the evaluation
