Question

Which statement is true about the polynomial
5s6t2 + 6st9 – 8s6t2 – 6t7 after it has been fully simplified?

It has 3 terms and a degree of 9.
It has 3 terms and a degree of 10.
It has 4 terms and a degree of 9.
It has 4 terms and a degree of 10.

Answer 1

\(5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7\) is this correct @liliana8611

Answer 2

old question but will attempt so it can be closed

you would identify any like terms (terms with the exact same combination of variables raised to the same exponents)

when every like term has been combined, to find the number of terms, count how many groups of numbers/variable combinations that are separated with + or - signs

ex:

___ + ___ - ____

is three terms

to find the degree, take each term, add up the exponents on the variables (remember that if a variable has no exponent it is assumed to have an exponent of 1), then the highest sum is the degree
