3x-2 over x²-2x-3 minus 1 over x-3 a. Rewrite the expression so that the first denominator is in factored form. b. Determine the LCD. (Write it in factored form.) c. Rewrite the expression so that both fractions are written with the LCD. d. Subtract and simplify.

Question

anonymous · Answer

Find the common denominator.
$$Hint:~~~~~~~\scr (x-3)(x+1)$$

anonymous · Answer

I mean that
$$x^2-2x-3=\scr (x-3)(x+1)$$

anonymous · Answer

2x−3
over
(x−3)(x+1)

anonymous · Answer

yes, and also, you can multiply everything times (x+1) in the second fraction

anonymous · Answer

so, is the LCD 1?

anonymous · Answer

(x+1)(x-3) is the LCD
