1. Can a polynomial contain more than one variable?
Yes, x3y2 + 3x2y + y4 is a polynomial in x and y of degree 5
2. Can a polynomial be divided?
Yes, a polynomial can be divided by another polynomial provided that the degree of the polynomial being divided is greater or equal to the divisor.
e.g. x3 + 2x2 − 5x − 6 can be divided by (x + 1)
This means that x3 + 2x2 − 5x − 6 = (x + 1)(x2+ x − 6)
