You can put this solution on YOUR website! QUESTION,
Given question is,
(4x^4-7x^2-19x)-5x-6x^2+10x^4)
Hope the question is ( 4x^4 - 7x^2 - 19x )- ( 5x - 6x^2 + 10x^4 )
First of all remove the parenthesis,
While doing the same the sign of each term inside the second parenthesis will change because there is a negative sign before that parenthesis,
===> 4x^4 - 7x^2 - 19x - 5x + 6x^2 - 10x^4
Collect like terms,
===> 4x^4 - 10x^4 - 7x^2 + 6x^2 - 19x - 5x
==> ( 4 - 10 ) x^4 - ( 7 - 6 ) x^2 - ( 19 + 5 ) x
==> ( -6) x^4 - ( 1 ) x^2 - ( 24) x
==> -6x^4 - 1 x^2 - 24x
==> -6x^4 - x^2 - 21 x
This is the simplified answer.
______________________________________________________________________________
If the submitted question is correct, that if it is like this,
(4x^4-7x^2-19x)-5x-6x^2+10x^4) you can use the same method.
that is,
(4x^4-7x^2-19x)-5x-6x^2+10x^4)
==> 4x^4-7x^2-19x -5x-6x^2+10x^4
Collect like terms and simplify,
==> 4x^4+10x^4-7x^2-6x^2-19x -5x
==> 14x^4 -13x^2 -24x
Hope You Understood.
Regards.
