Jabarkanlah setiap bentuk perkalian berikut ini.
1.(3x + 2). (3x - 2)
2.( 3x + 2y). (x - 5y)
3.(4x - 3y). (5x - 4y)
4.(p - 4). (p²+4p+16)
tolong jawab beserta jalannya
1.(3x + 2). (3x - 2)

3.(4x - 3y). (5x - 4y)
4.(p - 4). (p²+4p+16)
tolong jawab beserta jalannya
bisanya itu aja maaf yaaa
(3x+2)(3x-2) = 9x²-6x+6x-4
(3x+2)(3x-2) = 9x²-4
2. (3x+2y)(x-5y) = ...
(3x+2y)(x-5y) = 3x²-15xy+2xy-10y²
(3x+2y)(x-5y) = 3x² - 13xy -10y²
3.(4x-3y)(5x-4y) = ...
(4x-3y)(5x-4y) = 20x²-16xy-15xy+12y²
(4x-3y)(5x-4y) = 20x²-31xy+12y²
4. (p-4)(p²+4p+16) = ...
(p-4)(p²+4p+16) =p³+4p²+16p-4p²-16p-64
(p-4)(p²+4p+16) = p³-64
