jawabb cepetttt

3. kalikan bentuk berikut:

Jawaban:

$(2x + 3)(3x - 2) = {6x}^{2} - 4x + 9x - 6 = {6x}^{2} + 5x - 6$

$( - 4a + b)(4a + 2b) = - 16a^2 - 8ab + 4ab + 2 {b}^{2} = - 16 {a}^{2} - 4ab + 2 {b}^{2}$

$(x + y)(x - y) = {x}^{2} - {y}^{2}$

$(x + y)(x + y) = {x}^{2} + 2xy + {y}^{2}$

$(x - y)(x - y) = {x}^{2} - 2xy + {y}^{2}$
