Write the polynomial in standard form. 6x − 9 + 7x3 − 5x2

Question

i dont know what to do

Answer 1

Standard form means "descending order by degree".  Degree is the value of the exponent of the variable.

 

Your highest degree is 3 (the 7x³), so you write it first.  The next is -5x², so it is next. [Note: the - is with the 5x².]

 

 

Answer 2

6x − 9 + 7x³ − 5x²

 

=7x³ -5x² +6x -9
