factor 2x^2+7x15 = (2x3)(x1) factor x5/2x^25x+3 = (2x3)(x+5) can you find the LCD now?

Seems more like a GCF than an LCD, doesn't it? Odd question...

so does this mean that the lcd is (2x3)(x1)(x+5)?

I suppose so. If you had fractions where the first fraction had the first expression as a denominator and the 2nd fraction had the 2nd expression as its denominator, then the LCD would be the expression you just wrote...

The point, I guess, is that by factoring FIRST, you realize that (2x3) is actually a common factor, and so you wouldn't multiply by that... if you just multiplied the original expressions together to try to get the LCD, it would be a common denominator, but it wouldn't be the LEAST one... it would be too big by an extra factor of (2x3)
