What is rationalization?

the action of attempting to explain or justify behaviour or an attitude with logical reasons, even if these are not appropriate.

Thanks!

Rationalisation is a process by which radicals in the denominator of an algebraic fraction are eliminated.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
