Answer 2

Yes.

Answer 3

so how you think when there is a fractional equation with variable on denominator what is the first step what you need to do ? by what not can be equal the denominator never ?

Answer 4

0

Answer 5

so remember a fraction to not be

yes - good

Answer 6

so for what value of x you get the denominator zero ?

Answer 7

bc. the denominator has a x^2 term so this not will result a negativ number never

yes ?

Answer 8

yes

Answer 9

ok and now what you see what is in the numerator of this fraction ?

Answer 10
