Yes, although we generally refer to polynomials with two terms, like this one, as binomials.
The idea here is to multiply each term in the first polynomial by each term in the second polynomial.
x2 + x2 + x2 = (1 + 1 + 1)x2 = 3x2
Trinomials are polynomials with three terms. ie. x2+2x+1
x^2 + 3x - 2; -x^2 - 3x + 2andx - 1; 1 - x
x2 + x2 = 2x2
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
x2 + 48x + 320
x2 + x2 = 2x2
120
x4 +x2 =x2 (x2+1)
4x2 + x2 = 8 + x2
