Multiplying polynomials part 3

Question

Part 3

Answer 1

Answer 2

to multiply polynomial you should know first: constant and the variable (x)

then you multiply constant first and then the variable

like: 2x*3x²

constants are: 2 &3

variable: x &x²

2*3=6

x*x²=x³

so 2x*3x²=6x³

also you should know how to multiply variable:

first: they should be same base like: x²&x (x is the base)to add the exponent: 2+1=3

if they don't have same base like: x²&y then you cannot add the exponent then x²*y=x²y
