if a quadratic equation with real coefficients has a discriminant of -36 then what type of roots does it have
Aleks04 [339]

Step-by-step explanation:

We have,

If a quadratic equation with real coefficients has a discriminant of -36.

The general form of quadratic equation is :

ax^2+bx+c=0

The discriminant of this equation is : D=b^2-4ac

If D=0, it will have 1 real roots

If D>0, it will have 2 real roots

If D<0, it will have no real roots

We have,

D = -36 < 0, so, the quadratic equation will have no real roots.

What does "Classify the polynomial by the number of terms" mean
soldier1979 [14.2K]

"Classify the polynomial by the number of terms" means a term contains both the variables and its coefficient. For example a "monomial" has one term like 2x^{2}.

A binomial has 2 terms like 3x^{2}+6x

A trinomial has 3 terms like 4x^{2}+5x-8

And a polynomial has 4 or more terms.

So basically one can classify the type of polynomial by counting the number of terms in a given equation.
