Answer:

  (a)  There are two complex roots

Step-by-step explanation:

The discriminant of a quadratic function describes the nature of its roots:

  • <u>negative</u>: two complex roots
  • <u>zero</u>: one real root (multiplicity 2)
  • <u>positive</u>: two distinct real roots.

__

Your discriminant of -8 is <em>negative</em>, so it indicates ...

  There are two complex roots

_____

<em>Additional comment</em>

We generally study polynomials with <em>real coefficients</em>. These will never have an odd number of complex roots. Their complex roots always come in conjugate pairs.

Answer:

The factors of 2q²-5pq-2q+5p are (2q-5p) (q-1)....

Step-by-step explanation:

The given expression is:

2q²-5pq-2q+5p

Make a pair of first two terms and last two terms:

(2q²-5pq) - (2q-5p)

Now factor out the common factor from each group.

Note that there is no common factor in second group. So we will take 1 as a common factor.

q(2q-5p) -1(2q-5p)

Now factor the polynomial by factoring out the G.C.F, 2q-5p

(2q-5p) (q-1)

Thus the factors of 2q²-5pq-2q+5p are (2q-5p) (q-1)....

Explain how to find the reference angle for 1,406 degrees. Find the reference angle.
nataly862011 [7]
The reference angle is the smallest angle between the terminal ray and the x-axis.
 1406° mod 360° = 326°
The reference angle will be 360° -326° = 34°.
