Given the expression –10p2q + 7p3q – 5q, do the following as instructed below: A. Write the polynomial in descending order. B. Classify the polynomial by the number of terms C. State the degree of the polynomial.

????

ohh

I just need help with B and C

5. welshfella

there are 3 terms so its a tri - something

6. anonymous

trinomial

7. welshfella

right

8. welshfella

and the degree is the highest exponent

9. anonymous

Is it 8?

10. welshfella

in a particular term for example 6pq has degree 2 2p5q = degree 6

11. anonymous

do I add up the degrees?

12. welshfella

No not 8 look at each variable and add up the exponents

13. welshfella

5q is only 1 degree

14. welshfella

because its q^1

15. welshfella

ignore the numbers before the variables

16. anonymous

So it would be eight because p^2=2 and q=1 and p^3=3 right?

17. anonymous

I miss counted I actually got nine.

18. welshfella

No - you don't add up the exponents in all the terms you find the term which has the highest count of exponents Thats the degree

19. anonymous

So 7p^3q

20. welshfella

for example the trinomial x^2y + y^2 + y has degree 3 because x^2 y has 2+1 = 3 exponents

21. welshfella

yes 7p^3 q has highest degree 4

22. anonymous

Thanks!

23. welshfella

so the answer to C is 4

24. welshfella

yw

25. welshfella

so in descending order its 7p^3q -10p^2q – 5q
