Question

I have no clue how to even try and solve this....Can someone help me please. Its on my paper for math as pre-work to see how much we know....

Consider the following expression.
{3x-2 OVER x^2-2x-3 } - {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.

Answer 1

Any one able to help me?

Answer 2

For a.) X^2-2x-3, they want that in the form (X+-number )(X+- number ). That familiar

Answer 3

Kinda... So would it be (x-3)(x+1) correct?

Answer 4

YES

Answer 5

HELP ME

Answer 6

YA

Answer 7

On what?

Answer 8

A

Answer 9

OK

Answer 10

HELP ME

Answer 11

Okay and then wouldn't B. be.....give me a moment...

Answer 12

UMM OK

Answer 13

Would the least common factor be 1?

Answer 14

YES

Answer 15

Okay so how do I write that in factored form?

Answer 16

Okay so anyone who would like to use this for future reference:
question:
Consider the following expression.
{3x-2 OVER x^2-2x-3 } - {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.

the answers are:
a. (x+1)(x-3)
b. (x+1)(x-3)
c. {3x-2 0ver (x+1)(x-3)}-{(x+1) over (x+1)(x-3)}
d. 2x-3/(x+1)(x-3)
