Answer:
Algebra is the study of unknown factors (known as variables). Algebraic fractions are fractions with variables in the numerator or denominator, such as 36/x. Others include x2/y or 5x/y3. Since division by 0 is impossible, variables in the denominator have certain restrictions. The denominator can never equal 0. Therefore, in the fractions
36/x . . . x cannot equal 0
x2/y . . . .y cannot equal 0
5x/y3 . . .y cannot equal 0
m + 7
----------------------
(m - 6) (m + 2)
so, m-6 cannot equal 0, this means that m cannot equal 6, and
m + 2 cannot equal 0 also, this means that m cannot equal -2
36/x . . . x cannot equal 0
x2/y . . . .y cannot equal 0
5x/y3 . . .y cannot equal 0
[Edit]
Yes. Also called rational expressions.
An example:
----------------------
(m - 6) (m + 2)
so, m-6 cannot equal 0, this means that m cannot equal 6, and
m + 2 cannot equal 0 also, this means that m cannot equal -2
