A polynomial.
16 and 8
A quadratic polynomial must have zeros, though they may be complex numbers.A quadratic polynomial with no real zeros is one whose discriminant b2-4ac is negative. Such a polynomial has no special name.
No. It's a binomial, (whose value happens to be zero no matter what 'x' is).
To factor this, find two numbers whose product is 81 and sum 18. These two numbers are therefore 9 and 9. So we can rewrite the polynomial in its factored form as follows: (k+9)(k+9), or "k plus 9 squared"
prime
A polynomial.
If you know one linear factor, then divide the polynomial by that factor. The quotient will then be a polynomial whose order (or degree) is one fewer than that of the one that you stared with. The smaller order may make it easier to factorise.
14 and 28 are two even numbers between 10 and 30 whose greatest common factor is 14.
There are several possibilities of pairs of numbers whose greatest common factor is 18. 54 and 198 18 and 126 414 and 846 72 and 1422
