## anonymous 4 years ago When solving a rational equation what is the first step we must always take?

1. Hero

Find LCD or get rid of denominators

2. anonymous

rationalize the denominator

3. anonymous

...by multiplying the equation by "1", the fraction of the rational divided by the rational.

4. anonymous

would i square anything?

5. anonymous

Get rid of the denominator.

6. anonymous

Not really. For instance, in $4/\sqrt{3}$, you would rationalize it by multiplying th fraction by $\sqrt{3}/\sqrt{3}$, so it's similar to squaring the denominator. You would multiply the numerators, however, getting 4√3 in the numerator. In the denominator √3 times √3 is 3.

depends on the equation, for example √25=√(x+1) you would square it in this case 25=x+1 x=24
