Which expression is the greatest common factor (gcf) of the terms of trinomial 12x^7y^9 + 6x^4y^7 - 10x^3y^5

 2.  

Step-by-step explanation:

The given expression :

Term 1 :

Term 2 :

Term 3:

Lowest power of x = 3

Thus  , The highest common power of x =   (i)

Lowest power of y = 5

The highest  common power of y = (ii)

Greatest common factor of 12, 6 , -10= 2  [Because 2 is the largest number that divides all of them]   (iii)

From (i) , (ii) , (iii) , we have

Greatest common expression :

Hence, the correct answer is 2.

john has 55 candy left.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
