Question

solve equation

(wait while i draw it)

Answer 1

Try multiplying both sides by \((10+x)(10-x)\).

Answer 2

Don't do that, just take lcm and subratct/add, you can't multiply since it can be equal to zero

Answer 3

@rahul1995 - This is an equation, not a function. That reasoning applies to functions. Here, you'd have to restrict \(x \ne \pm 10\) anyway.

Answer 4

Oh you're right, I stand corrected, Sorry for the confusion
