Find the product of (4x + 3y)(4x − 3y). A) 16x^2 − 24xy + 9y^2 B) 16x^2 − 9y^2 C) 16x^2 + 24xy + 9y^2 D) 16x^2 + 9y^2
(4x + 3y)(4x -3Y) = 16x^2 +12xy - 12xy - 9y^2 =
HOLY HELL. I have no clue.
you are just multiplying each each by eaxh number
well since the middle terms are the same you can get rid of them which leaves you the answer
(4x + 3y)(4x − 3y) 4x.4x - 4x.3y + 3y.4x -3y.3y 16x^2 -12xy+12xy-9y^2 16x^2-9y^2
Find the product of (3x + 7y)^2. A) 9x^2 − 42xy + 49y^2 B) 9x^2 − 49y^2 C) 9x^2 + 49y^2 D) 9x^2 + 42xy + 49y^2
(3x+7y)(3x+7y) 3x.3x+21xy+21xy+7y.7y 9x^2+42xy+49y^2
