Question

Write the properties of addition and subtraction of polynomial

​

Answer 1

The main thing to remember is to look for and combine like terms. You can add two (or more) polynomials as you have added algebraic expressions. You can remove the parentheses and combine like terms. Regroup using the commutative property of addition and the associative property of addition

Answer 2

Answer:

$\bold{\boxed{\underline{\pink{\tt{Properties \ of \ Addition \ of \ Polynomial}}}}}$

• Sum of two positive integer is a positive integer.

Example : 7 + 5 = 12

• Sum of two negative integer is a negative integer.

Example : (-7) + (-5) = -7 -5 = -12

• Sum of a positive integer and negative integer is positive, if positive integer is greater than the negative integer.

Example : (+7) + (-5) = +7 -5 = +2

• Sum of a positive integer and negative integer is negative, if negative integer is greater than the positive integer.

Example : (-7) + (+5) = -7 +5 = -2

$\bold{\boxed{\underline{\pink{\tt{Properties \ of \ Subtraction \ of \ Polynomial}}}}}$

• Product of two positive integer is a positive integer.

Example : +7${\multiplication}$+5 = +35

• Product of two negative integer is a positive integer.

Example : -7${\multiplication}$-5 = +35

• Product of positive and negative integer is a negative integer.

Example : +7${\multiplication}$-5 = -35

• Product of negative and positive integer is a negative integer.

Example : -7 ${\multiplication}$ +5 = -35

Hope it helps uh mate :)
