Subtract the polynomials (9x2+17x+13)−(2x2+12x+11) ( 9 x 2 + 17 x + 13 ) − ( 2 x 2 + 12 x + 11 )
(9x^2 + 17x + 13) - (2x^2 + 12x + 11)
To subtract the polynomials, we need to subtract the corresponding terms.
The x^2 terms: 9x^2 - 2x^2 = 7x^2
The x terms: 17x - 12x = 5x
The constant terms: 13 - 11 = 2
Therefore, the difference of the polynomials is 7x^2 + 5x + 2.
