When solving a rational equation why is it necessary to perform a check?
It is important to check your answers to make sure that it doesn't give a zero denominator in the original equation. When we multiply both sides of an equation by the LCM the result might have solutions that are not solutions of the original equation. We have to check possible solutions in the original equation to make sure that the denominator does not equal zero. There is also the possibility that calculation errors were made in solving.
What is the LCM of 35x to the 8 power and 245x to the 7 power?
Well, let's start by breaking down the numbers and variables. The LCM, or least common multiple, is the smallest multiple that both numbers share. For 35x^8 and 245x^7, we can see that the common factors are 5, 7, and x^7. So, the LCM would be 5 * 7 * x^7, which simplifies to 35x^7.
