The sum of two polynomials is 10a²b2 - 8a²b + 6ab2 - 4ab + 2. If one addend is -5
other addend?

  10a²b² -8a²b +6ab² -4ab +7

Step-by-step explanation:

If P represents the given polynomial (sum), and A represents the unknown addend, it appears you have ...

  A + (-5) = P

You want to find A. You can do that by adding 5 to both sides of this equation:

  A = P +5

Adding 5 to the given polynomial gives you ...

  10a²b² -8a²b +6ab² -4ab +7 . . . . the other addend

how is that middle school

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
