Given that the value of polynomial 5x & # 178; - 6x + 10 is 5, then what is the value of 5x-3 of 6

Given that the value of polynomial 5x & # 178; - 6x + 10 is 5, then what is the value of 5x-3 of 6

5x²-6x+10=5
5x²-6x=-5
Divide both sides by 5
x²-6x/5=-1
It should be 6x out of 5
So the original formula = - 1-3 = - 4

When x is equal to 3 and - 3 respectively, the value of polynomial 6x2 + 5x4-x6 + 3 is ()
A. Opposite to each other B. reciprocal to each other C. equal D. different sign

Some analysis shows that when x is equal to 3 and - 3 respectively, the values of polynomial 6x2 + 5x4-x6 + 3 are equal

It is known that the sum of a polynomial and the polynomial 5x-8-x ^ 3 is 2x ^ 3-3x ^ 2 + 6x + 5

3x^3-3x^2+x+13

Given the complete set u = {1,2,3,4,5}, a = {x | x2-5x + M = 0}, B = {x | x2 + NX + 12 = 0}, and (∁ UA) ∪ B = {1,3,4,5}, can you find the value of M + n?

Let u = {u = {1,2,2,3,4,4,5}, (∁ UA) \∪ B = {1,3,4,4,4,5}, {2} {u = u = {1,2,2,2,2,3,3,4,4,5}, (\ UA) 8746; B = {1,3,3,4,4,4,4,4,4,4,5} \\8705\\\\8705\\\\\\\\\\\\\\\\\3, 4}. M + n = - 1
