The stamp "B 25" on a ring typically indicates that the piece is made of 925 sterling silver. The "B" stands for the brand or manufacturer, and "25" signifies the silver content, which is 92.5%, a standard for sterling silver.
I have a ring, it has a ruby red stone and it's silver and it has B25 on it, how much is it worth
If you see the imprint of "B 25" stamped on a ring, the "B" most likely represents a specific date. The "25" represents the quality of the gold or the karat.
925 represents the purity of silver being 92.5% pure. The letter "B" most likely represents a date code.
If the 'B' comes before the 10k it's a maker mark, after the 10k it's gold over something else. I have a gold ring marked ( B10k ) it's real 10kt I've been wearing it for years now and no change. But mine is Victorian pretty old.

If you mean: b squared+b+25 then the given quadratic expression can't be factored because its discriminant is less than zero.
(a+b)/2 = 25 (a*b)^0.5 = 20 a = 400/b b^2-50b+400=0 b=40, b=15 a=15, a=40
