It's a good question.
First need to simplify and then plugin as below:
Quantity A: \(5b^2\) – 10b + 7
Quantity B: b
So, we can add 10b on both Quantities, because the inequality will not change i.e:
Quantity A: \(5b^2\) + 7
Quantity B: 11b
Now, don't plugin -ve values, because Quantity A will always greater (being positive). Also in 0, Quantity A will be greater.
Finally, just check for positive values. You will see Again, Quantity A always greater.
For positive values, just plugin one value from (0 - 1) and other one from any value greater than 1.
Choice
Choice A is correct.
