Oh, I think you can do sqrt(x^4), and sqrt(25)

Find the square root of x^4 and 25 = x^2 and 5 Difference of squares: (a+b)(a-b) (x^2-5)(x^2+5)
anonymous
  • anonymous
You can use FOIL to expand it back out and you will get x^4-25
anonymous
  • anonymous
thanks .
anonymous
  • anonymous
then either at x^2=5 or x^2=5
anonymous
  • anonymous
sorry it will be x^2=5 or x^2=-5
anonymous
  • anonymous
on squaring in x^2=5 the value of x will be 25
anonymous
  • anonymous
and on squaring x^2=-5 the value of x will be the same 25
anonymous
  • anonymous
thanks @koli123able.
anonymous
  • anonymous
how did you get to x^2=5 or x^2=-5 explain plz. thanks
anonymous
  • anonymous
yes can i help you
anonymous
  • anonymous
ANYONE THERE
anonymous
  • anonymous
yes
anonymous
  • anonymous
please take it from the top.
anonymous
  • anonymous
x^4-25
anonymous
  • anonymous
sorry i type too wrong
anonymous
  • anonymous
(x)^2 - (5)^2
anonymous
  • anonymous
opening it by formula (a - b)^2
anonymous
  • anonymous
you squared it!
anonymous
  • anonymous
(x-5)^2
anonymous
  • anonymous
take 2 power common
anonymous
  • anonymous
sure

  • anonymous
did u get it till here
anonymous
  • anonymous
yes. thanks
anonymous
  • anonymous
now u can solve it further but this answer is absoluteley right
anonymous
  • anonymous
so what about "x^2=5 or x^2=-5 "
anonymous
  • anonymous
|dw:1343915068883:dw|
anonymous
  • anonymous
suppose it as an equation in some parts of world they solve it by this too
anonymous
  • anonymous
but this is am expression!! dose that last bit matter?

anonymous
  • anonymous
bless you . your so helpful . |dw:1343915234400:dw|
anonymous
  • anonymous
the whole asked to factorize the result is at the top but if someone says factorize and get the values of variable then u need to get a bit further
anonymous

|dw:1343915283974:dw|
anonymous
  • anonymous
|dw:1343915322903:dw|
anonymous
  • anonymous
i see . so an an equation i need to finde the vales of x in this case!!! right
anonymous
  • anonymous
Thus, the Solution Set is {25,25}
anonymous
  • anonymous
right
anonymous
  • anonymous
bye
