Answer:
Step-by-step explanation:
(−2x + 6y)(4x − 6y)
To multiply this we use FOIL method
first we multiply -2x with 4x, it becomes -8x^2
Then multiply -2x with -6y, we get 12xy
multiply 6y with 4x, we get 24xy
multiply +6y with -6y, we get -36y^2
Now we commbine all the answers we got
combien like terms
12xy+24xy= 36xy
