Answer 1

Answer:

Note: dividing by a fraction is the same as multiplying by the reciprocal of the fraction.

In some cases of simplifying an algebraic expression, the expression will be a fraction. For example,

x2+3x

x+3

has a quadratic binomial in the numerator and a linear binomial in the denominator. We have to apply the different factorisation methods in order to factorise the numerator and the denominator before we can simplify the expression.

x2+3x

x+3

=

x(x+3)

x+3

=x(x≠−3)

If x=−3 then the denominator, x+3=0 and the fraction is u
