Answer:

Addition of algebraic expressions :

addition of algebraic expressions ex.

Add

(3x3+2x–5)+(2x3+x+9)collecting like termsadding like terms=3x3+2x3+2x+x−5+9=(3+2)x3+(2+1)x+(−5+9)=5x3+3x+4

this is how we add algebraic expressions

Subtraction of algebraic expressions :

subtraction of algebraic expressions ex.

Subtract

(4x3+x2+x+6)–(2x3−4x2+3x+5)=4x3+x2+x+6−2x3+4x2−3x–5=4x3−2x3+x2+4x2+x−3x+6–5=2x3+5x2–2x+1

this is how we subtract algebraic expressions.
