Witryna1. Fractions. Let a,b,c, and d be numbers. (a) You can break up a fraction from a sum in the numerator, but not in the denom-inator: a+b c = a c + b c but a b+c 6= a b + a c (b) Cancellation of the c here requires that it appears in each additive term of the numerator and denominator: ca+cb cd = c(a+b) cd = a+b d but ca+b cd 6= a+b d WitrynaWolfram has it written as $(a^2+b^2)(c^2+d^2)=(ac\pm bd)^2+(bc\mp ad)^2$. I believe the book wrote them separately. With the same variables, that yields $(ac+bd)^2+(bc …
