what did you get? And next time, i recommend you go to the Calculus section, not the math.

yup correct ur error, u'll get used to the method by practicing
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
it's ok to make error because from them u learn, but don't get turned off because of errors and ur close in ur answer
 one year ago

JaweriaBest ResponseYou've already chosen the best response.0
ok i know that numerator will be 2 but under radical is that also wrong?
 one year ago

JaweriaBest ResponseYou've already chosen the best response.0
i m sorry i know i am asking too many stupid questions
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1

can u solve the rest and tell me where did u make the mistake
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
now ur final answer should be

JaweriaBest ResponseYou've already chosen the best response.0
I m actually multiplying 2x by the power of 2 so its 4x and multipylinh 5 by the power of 2 so its giving me 25
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
by the way give me the other 2 equations so u try and i try to solve the problem
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
and this way we can save time
 one year ago

JaweriaBest ResponseYou've already chosen the best response.0
but before I do that one more question just one last time can you please show me that how you got that answer on the numerator is 1 and denominator is different too.

yeah sorry i was focusing deeply to that answer
 one year ago

JaweriaBest ResponseYou've already chosen the best response.0
sorry one more question
 one year ago

JaweriaBest ResponseYou've already chosen the best response.0
how you got 5 under that radical?
 one year ago

JaweriaBest ResponseYou've already chosen the best response.0
bcoz once you took 4 out then 10 doesnt come into table of 4
 one year ago

JaweriaBest ResponseYou've already chosen the best response.0
but how we are getting 20?
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
because (2x+5)^2= 4x^2 + 20x +25
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
4x^2+20x+24, 4(x^2+5x+6)

JaweriaBest ResponseYou've already chosen the best response.0
ok but once you will cancel that 2 out from denominator of 4, arent you not suppose to get 2 in denominator?
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
not because its root4=2
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
remember we took the 4 out of the root

JaweriaBest ResponseYou've already chosen the best response.0
yeah we did take the 4 out from the root but we are also canceling that 2 with 4 right?
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
so u can see when we took the 16 out of the root it became 4
 one year ago

mathsmindBest ResponseYou've already chosen the best response.1
no cancelling the 2 with root4
