can someone explain this process of simplifying in more detail. I'm so confused
especially from the first to second step .. thanks
@hartnn
its just factoring out common terms
but how though
how did the (3x+4)^5 and (3x+4)^4 become (3x+4)^4 and (3x+4)^1
from the first step to the second
\(\Large a^5 +a^4 = a^4 (a+1)\)
thats what is done with 3x+4 terms a=3x+4
hmm let me think about it for a it and ill get back to u :P
sure :)
so if it was (3x+4)^5 and (3x+4)^3.. how do we factor out the like term
we would have factored OUT (3x+4)^3 so, (3x+4)^5 would have become (3x+4)^2
and (3x+4)^3 would have become 1 (3x+4)^3 [(3x+5)^2 + 1]
(3x+4)^2 i mean***
sorry I'm confused :P
\(\large ☻☺+☻♥= ☻(☺+♥) \\ \text{this is factoring, } \\ \text{☻ was common from both terms and factored out.}\)
you have something like \(a (3x+4)^5 + b (3x+4)^4\) right?? a,b are some functions of x which we are not concerned with now.. your doubts is how do we get to here : \(a (3x+4)^5 + b (3x+4)^4 = (3x+4)^4 [a (3x+4) +b]\) right ?
yes
\(\Large (3x+4)^5 = (3x+4)^4 \times (3x+4)\)
oh yea because the if u add the exponents 4+1 it is equal to 5
YES, thats correct. \(a (3x+4)^5 + b (3x+4)^4 = a (3x+4)^4 (3x+4) + b (3x+4)^4\) n0w (3x+4)^4 is common! and can be factored out
oh ok and same goes with (x^3-x+2) in the same question i gave
yes, correct
(x^3-x+2)^2=(x^3-x+2)^1+(x^3-x+2)^1
\((x^3-x+2)^2=(x^3-x+2)^1\times (x^3-x+2)^1\)
\(a^2 = a \times a\) not a+a
ph yes sorry ... thanks a lot
oh*
ask if any more doubts :) welcome ^_^
