CAn someone help me its a emergency

(a+b)(a-b) = a² - b²
Think of applying this identitiy here: x² - 16 = x² - 4²
If seeing so many fractions confuses you, write the numerator (1/x+4 + 1/x-4) and multiply it by the reciprocal of the denominator separately (1/(x/x²-16) + 1/x+4))

so like this?

so i make the one at the bottom rifht like this so i can combine them

[west turtle]

Yup

[queen sorrel]

is it right

i did the bottom part like this

srry for my bad handwriting

is the top like this

and then i combine them

so its like :2x
_____
(x+4)(x-4)

then i can do the rest

[west turtle]

Yup

Denominators of each numerator and denominator cancel out directly (x²-16)

Thanks

Yea ik
