whats the lowest common denominator LCD with x^2-25 and x+5

Since x^2 - 25 = (x+5)(x-5),

I'd say x+5 is the greatest common divisor.

Since we have no fractions, I don't think we can talk about denominators. (Unless we are in fact talking about denominators of fractions whose numerators are unspecified ...)

oops. In that case, then (x^2-25) would be the LCD.

To find the lowest common denominator (LCD) between the expressions x^2-25 and x+5, we need to factor both expressions and identify their common factors.

First, let's factor the expressions:
x^2-25 can be factored using the difference of squares formula: (x+5)(x-5).
x+5 cannot be factored further.

Now, let's identify the common factors:
The common factor between (x+5) and (x+5)(x-5) is (x+5).

Therefore, the lowest common denominator (LCD) between x^2-25 and x+5 is (x+5)(x-5).

To find the lowest common denominator (LCD) between two expressions, we need to factorize each expression completely and identify the common factors.

Let's start with the expression x^2 - 25. This is a difference of squares, which can be factored as (x - 5)(x + 5).

Next, we have the expression x + 5, which is already in its factored form.

Now, we need to identify the common factors between these expressions. In this case, both expressions have a factor of (x + 5).

To find the LCD, we multiply all the factors together. Therefore, the LCD is (x - 5)(x + 5).

In conclusion, the lowest common denominator (LCD) for x^2 - 25 and x + 5 is (x - 5)(x + 5).
