I need the answer to this question please

1 answer:

8 0

X^2 + x < 20
x^2 + x - 20 <0
set the left side equal 0

(x+5)(x-4) = 0
x + 5 = 0; x = -5
x - 4 = 0 ; x = 4

so solutions:
x has to be between -4 and 5 means
-5 < x < 4

What is the LCD of x-3, x+3, and <img src="https://tex.z-dn.net/?f=x%5E2-9" id="TexFormula1" title="x^2-9" alt="x^2-9" align="ab

The least common denominator is one, since all of these numbers are actually whole numbers. They're actually all $\frac{x-3}{1} \frac{x+3}{1} \frac{x^2-9}{1}$
If you mean the greatest common factor, then it's obviously $x$
