From the sum of polynomials 3a2−ab−2b2 and 2a2+5ab−3b2 subtract polynomial a2−3ab−4b2.

Step-by-step explanation:

First, we will sum

and

Then, from that sum, we will SUBTRACT  

First, lets take the sum by combining like terms:

Now, lets do the subtraction:

This is the answer.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

the answer is about 24 dollars
