a^2+ma+1/9=(a+n)^2=a^2+2na+n^2
n^2=1/9,n=±1/3
M = 2n = ± 2 / 3, and the sign is the same as n
1/3x^2-3=1/3(x^2-9)=1/2(x+3)(x-3)
a^2-10a+(25)=(a-5)^2
9x^2+kx+16=(3x+4)^2=9x^2+24x+16,k=24
x^3-xy^2=x(x^2-y^2)=x(x+y)(x-y)
x^3-25x=x(x^2-25)=x(x+5)(x-5)
x^3-6x^2+9x=x(x^2-6x+9)=x(x-3)^2

The square of M-N
Do not change the value of the fraction so that the sign before the square of n is positive

=[(-1)×(m-n²)]/(1+m²)
=(n²-m)/(1+m²)

Calculate 18 ^ m △ 3 ^ n

=(3^2×2)^m÷3^n
=2^m×3^2m÷3^n
=2^m×3^(2m-n)
