Four polynomials are shown below: a. 4 − 7x5 + x2 b. 5x3 + 5 − 3x4 c. 3x + 2x4 − x2 + 6 d. 3x3 − 5 + 2x5 + x which of the above polynomials is a 4th degree trinomial? polynomial a polynomial b polynomial c polynomial d

Polynomial B

Step-by-step explanation:

We are given 4 different polynomial. We need to choose 4th degree polynomial from given.

Degree is maximum power of x of polynomial.

Option A:

Degree = 5,  False

Number of term = 3 (Trinomial)

Option B:

Degree = 4

Number of term = 3 (Trinomial)

True

Option C:

Degree = 4

Number of term = 4 (Not Trinomial)

False

Option D:

Degree = 5

Number of term = 3 (Trinomial)

False

Hence, Polynomial B is correct whose degree 4 and number of term 3.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
