By multiplying each the numerator and denominator by the LCM, we basically introduce an element of 1 into the expression. This doesn’t change the worth of the fraction as a result of multiplying by 1 is equal to multiplying by the multiplicative id.
Nevertheless, this multiplication has a big impact on the denominator. As a result of the LCM is divisible by all of the elements of the denominator, multiplying by it ensures that every one the elements of the denominator at the moment are current within the denominator of the brand new expression. Because of this x can now be canceled out from the denominator, leaving us with an expression that’s now not undefined at x = 0.
For instance, contemplate the fraction 1x. The LCM of the denominator is solely x, so we multiply each the numerator and denominator by x to get xx^2. We will now cancel out the widespread issue of x within the numerator and denominator, leaving us with the simplified expression 1/x.
Multiplying by the LCM of the denominator’s elements is a basic step in fixing fractions with x within the denominator. It permits us to get rid of x from the denominator whereas preserving the worth of the expression, making certain that the ensuing expression is well-defined for all values of x besides zero.
