Question

simplifying rational expressions

which of the following is equal to therational expression when x=3 or -10

(x+5)(x-3)/(x-3)(x+10)

Answer 1

explain this to me pleaseeee..

Answer 2

like before, the denominator can't be 0, so when x = -10, it's undefined.

Answer 3

but when x= 3, the numerator turns into 0, that works.

Answer 4

when \[x \neq 3\] or -10

Answer 5

im soo lost?

Answer 6

sorry, I was wrong

Answer 7

when x = 3, it becomes undefined as well

Answer 8

so x can't be 3 or -10.

Answer 9

then you can just simplify the expression by cancel x-3 from the numerator and denominator.

Answer 10

so its x+5/x+10

Answer 11

so your answer is (x+5)/(x+10). You are right!

Answer 12
