Exercise 17 Page 248

Substitute -9 for d and 36 for f in the expression. When dividing real numbers, the quotient will be positive if the signs are the same and it will be negative if the signs are different.

Practice makes perfect
To evaluate the given expression for d=-9 and f=36, first, we should substitute these values into the expression and simplify.
f^2/d^2
36^2/( -9)^2
36(36)/(-9)(-9)
36(36)/9(9)

When dividing real numbers, the quotient will be positive if the signs are the same and it will be negative if the signs are different. cc Same Sign & Different Signs (+)Ă·(+)=(+) & (+)Ă·(-)=(-) (-)Ă·(-)=(+) & (-)Ă·(+)=(-) In our case both numbers are positive, so the quotient will be positive.
