Use the discriminant to describe the roots of each equation. Then select the best description.
Marrrta [24]
Let's find the discriminant of <span>x^2+9x+14=0.  Here, a=1, b=9 and c=14.

The discriminant is b^2-4ac.  Substituting the above numeric values,
                                9^2-4(1)(14) = 81-56 = 25

The sqrt of 25 is 5.  Thus, your polynomial has two unequal, real roots.

Off the point example:  If the discriminant were zero, your poly would have two real, equal roots.</span>

What is the degree of the polynomial?
DIA [1.3K]

Answer:

2

Step-by-step explanation:

The degree of the polynomial is the highest exponent of an expression. When more than one variable is present, its is the sum of exponents on one term in the expression.

The polynomial has terms xy, 3x^2, -7 and x. The term with the highest exponent sum is xy or 3x^2. Both have degree 2. The degree of the polynomial is 2.
