Question

(x + 7)/
(25x^2 − 49)
÷
(x^2 + 11x + 28)/
(5x^2 + 23x − 42)

Answer 1

Factor the difference of squares in the denominator.

Answer 2

i know that but i cant figure it out

Answer 3

The numerator should be "5x+7", I didn't see that.

You can do partial fractions if you're working on calculus, otherwise, I's assume it's a mistake.

Answer 4

im lost completely on the factoring

Answer 5

Sorry, I didn't see the division sign on its own line.

See if this helps. From top to bottom, the lines factor as follows:

1. Factored
2. (5x-7)(5x+7)
3. (x+7)(x+4)
4. (5x-7)(x+6)

Answer 6

Does that help?

Answer 7
