If the polynomial of x-4x ^ 3-2mx ^ 2 + 2x ^ 2-5 is a cubic trinomial, then M satisfies the condition () A.m=-1 B.m≠1 C.m=1 D.m≠1

If the polynomial of x-4x ^ 3-2mx ^ 2 + 2x ^ 2-5 is a cubic trinomial, then M satisfies the condition () A.m=-1 B.m≠1 C.m=1 D.m≠1


C.m=1



When x is the value, the value of cubic polynomial x ∧ 3-3x ∧ 2-4x is equal to - 12


The original problem is equivalent to x ^ 3-3x ^ 2-4x + 12 = 0
Polynomial x ^ 3-3x ^ 2-4x + 12 = (x + 2) * (X-2) * (x-3)
So the solution is
X = 2 or x = - 2 or x = 3



If 4x ^ 2 + X + m is a complete square, then M is equal to?


4m=(1/2)²
m=1
