If the quadratic trinomial x ^ 2-6x + m ^ 2 is a complete square, then the value of M is
The quadratic trinomial x ^ 2-6x + m ^ 2 is a complete square number
Namely: x ^ 2-2 * x * 3 + m ^ 2
Then m ^ 2 = 9
m=3,m=-3
It is known that (M-4) x ^ | m | - 2-3x + 1 represents the value of quadratic trinomial m and what is it
|M | - 2 = 2 and m ≠ 4
∴ m=-4
The original formula is
-8x^2-3x+1
When k why, k-6x + 9x quadratic is a complete square
K = 1, is the square of (1-3x)
