- maheshmeghwal9

ya

- jhonyy9

ok than answer my questions

- maheshmeghwal9

ok

- jhonyy9

than you need get the common denomminator
yes

- jhonyy9

but firstly what will be the restriction for x values ?

- jhonyy9

when a fraction will be undefined sure ?

- maheshmeghwal9

when we divide it by zero.

- jhonyy9

so when the denomminator is zero YEs ?

- jhonyy9

so than look it there when will be zero these denominators ?

- maheshmeghwal9

for 4 & 2.

- jhonyy9

so than these restrictions for x will be that x not can being equal never 4 and 2

denominator

- jhonyy9

no

- maheshmeghwal9

common

- jhonyy9

?

- maheshmeghwal9

yes

- jhonyy9

than what will be ?

- maheshmeghwal9

(x-4)(x-2)

- maheshmeghwal9

(x-2)^2 =x^2 -16
x^2 -4x +4 =x^2 -16
-4x+4=-16
-4x=-20
x=5

- maheshmeghwal9

i have solved before

- jhonyy9

how was there x=10

- jhonyy9

???

- maheshmeghwal9

no you see next solution.

- maheshmeghwal9

which i have done

- jhonyy9

ok i see it but befor you have wrote there x=10

- maheshmeghwal9

ya there I was wrong. So thanx for your co-operation.

- jhonyy9
