The things that learnt this week are Multiplying and dividing rational expressions, Addition and subtraction of rational expressions, Addition/Subtraction with “ugly” denominators.
The strategies for multiplying and dividing rational numbers can be uesd to multiply and divide rational expressions. All non-permissible values of each expression being multiplied or divided must be stated.
how to solve it:
Divide the numerators and denominators by their common factors. Multiply the numerators. Multiply the denominators.
Since division by 0 is not permitted, any value that makes the numerator of the divisor 0 is a non-permissible value.
When the polynomial in numerator or denominator is a binomial or trinomial, it may be factored before simplifying the expression.
