It is known that the quadratic power of m-2 + MX-3 of polynomial (m-2) x is about the quadratic trinomial of X It is known that the square-2 + MX-3 of the polynomial (m-2) XM is a quadratic trinomial of X, and the value of M is obtained.

It is known that the quadratic power of m-2 + MX-3 of polynomial (m-2) x is about the quadratic trinomial of X It is known that the square-2 + MX-3 of the polynomial (m-2) XM is a quadratic trinomial of X, and the value of M is obtained.

∵ the quadratic power of m-2 + MX-3 of polynomial (m-2) x is about the quadratic trinomial of X
That is, (m-2) x ^ (M & # 178; - 2) + MX-3
The above polynomials are quadratic trinomials of X
∴m-2≠0 m²-2=2
The solution is m = - 2
