Sign In
Factor the denominator in the first fraction to get the same denominator as in the second fraction.
Factor the denominator in the first fraction and expand the denominator in the second fraction to get the same denominator.
Dividing by a fraction is the same as multiplying the first fraction by the reciprocal of the second fraction.
Factor the polynomials before carrying out the multiplication.
3x^2+x-3/x(2x-1)(x+5)
3x-5/2x+3
x+4/4x-3
m+5/m+4
We want to add the given rational expressions.
x-4/2x^2+9x-5 + x+3/x^2+5x
To add the fractions they need to have the same denominator. Therefore, let's start by factoring the denominator.
Next, we will rewrite the denominator in the second fraction. Notice that we will substitute the denominator in the first fraction with its factored form.
Factor out x
a/b=a * x/b * x
a/b=a * (2x-1)/b * (2x-1)
Commutative Property of Multiplication

The fractions have now been added. Since it is not possible to factor out a common factor in the numerator, we cannot simplify the fraction. However, we can simplify the numerator if we distribute and multiply the parentheses.

Add and subtract terms
We are given the difference between two rational expressions.
4x^2-11x+6/2x^2-x-6 - x+2/2x+3
The first step is to rewrite the fractions so that they have the same denominator. Since the first denominator is a quadratic trinomial, we can try to factor it.
To get the same denominator, we need to expand the second fraction with (x-2). Notice that we will substitute the denominator in the first fraction with its factored form.
a/b=a * (x-2)/b * (x-2)
(a+b)(a-b)=a^2-b^2

To simplify the fraction further we want to factor the numerator.
Commutative Property of Multiplication
Write as a product of fractions
a/a=1
Identity Property of Multiplication
Since the numerator and denominator are in factored form already, we can carry out the division straight away. Dividing two fractions is the same thing as multiplying the first one with the second fraction's reciprocal.
a/b÷c/d=a/b*d/c

We want to multiply the given rational expressions.
2m^2+7m-15/m^2-16*m^2-6m+8/2m^2-7m+6
Before we multiply the fractions, we want to factor each expression to make the multiplication easier. Let's start with the numerator in the first fraction.
We will continue with the denominator, which we can factor to a product of two binomials.
We now have the second fraction left, and once again we will start with the numerator.
Finally, we want to factor the denominator in the second fraction.
We can now substitute the polynomials with their factored form and then multiply the fractions and try to find Giant Ones.
