Proof: no matter a, B take any real number, the value of polynomial a * b * + b * - 6ab-4b + 14 is not less than 1 | Math enthusiast | Mathematical art

Proof: no matter a, B take any real number, the value of polynomial a * b * + b * - 6ab-4b + 14 is not less than 1

a^2*b^2+b^2-6ab-4b+14
=(ab-3)^2+(b-2)^2+1
>=0+0+1
=1
Therefore, no matter a and B are any real numbers, the value of polynomial a * b * + b * - 6ab-4b + 14 is not less than 1
