Find the degree of the polynomial 9x^3 y6 + 2.5xy + x^2 .

1 answer:

6 0

The degree of the polynomial is 9 ( not determined by the first number)
The degree of a polynomial is the highest exponent.
Here the highest exponent is 6 but since y is not a term on its own, you add the exponent of the term together.

I need help with this please !! I have to use the tabular method which is using like the boxes. Thank you!!

NikAS [45]

Answer:

a. 12 - 8x - x² + x³

b. 275 - 375x - 351x² + 240x³ + 112x⁴

c. 30 + 37m - m² - 25m³ - 14m⁴ + 3m⁵

d. 81 + 9x² + x⁴

Step-by-step explanation:

Tabular method is what I hear people call "Partial Products". Alright. All you have to do is look at how many terms are in each factor, break them up separately into columns and rows, then do your multiplication. This is the best example you will get, and just so you know, it is NOT drawn to scale [IMPERFECT]:

9 | -3x | x²

------|-------|-----

9 | 81 | -27x | 9x²

____________________

3x | 27x| -9x² | 3x³

| | |

____________________

x² |9x² | -3x³ | x⁴

| | |

Add up all the boldfaced terms inside the box, and you will get the above answer.

I am joyous to assist you anytime.
