Question

(15x^4+2x^3-x2+8x-5)-(9x^4+3x^2-2x-13)

Answer 1

`(6x^(4) + 2x^(3) -4x^(2)+ 10x + 8)`

Explanation:

Given equation as :

`(15x^(4) + 2x^(3) - x^(2) + 8x -5 ) - (9x^(4) + 3x^(2) - 2x - 13)`

Or,
`(15x^(4)- 9x^(4))+ 2x^(3) + ( - x^(2) -3x^(2)) + (8x + 2x)+ (-5+13)`

`(6x^(4) + 2x^(3) -4x^(2)+ 10x + 8)` Answer
