A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Let the number be m & n

Hence

mn = -8

m + n = 1

It follows that m = -8/n

Substitute

-8/n + n = 1

Multiply through by 'n'

-8 + n^2 = n

n^2 - n - 8 = 0

This does NOT factor so Complete the Square

n^2 - n = 8

(n - 1/2)^2 - (1/2)^2 = 8

(n - 1/2)^2 - 1/4 = 8

(n - 1/2(^2 = 8 1/4 = 33/4

Square Root both sides

n - 1/2 = +/-sqrt(33) / 2

n = 1/2 +/- sqrt(33) / 2

or

n = (1 +/- sqrt(33))/ 2
