How can you add brackets in this question?
5x3-2x10-3=47
do you mean 5x^3 - 2x^10 - 3 = 47 ?
If you want to factorise properly you would change it to
You'd change it to 2x^10 - 5x^3 +50 = 0
then look for factors.
The only possible rational factors are +- ( 1,2,5,25,50,0.5,2.5, 12.5) Using rational root theorem
Using remainder theorem I can see that;
no minus one will work so that halves the possibilities
2 or bigger won't work
1 doesn't work
0.5 doesn't work
so there are no rational roots so I can't factorise
However, I suppose you could say
5x^3 - 2x^10 - 3 = 47
x^3(5 - 2x^7) = 50
It wouldn't be very useful for anything but it does have brackets and it is true.
