Question

1. (x-y) (2x-y)
2. (4c+2) (2c+3)

tolong bantu ya kak pake caranya

Answer 1

Yang nomor 1
(x - y)(2x - y)
x(2x) + x(- y) - y(2x) - y(- y)
2x² - xy - 2xy + y²
2x² - 3xy + y²

Yang nomor 2
(4c + 2)(2c + 3)
4c(2c) + 4c(3) + 2(2c) + 2(3)
8c² + 12c + 4c + 6
8c² + 16c + 6

Answer 2

1.(x-y) (2x-y)=2x^2-xy-2xy+y^2
2x^2 - 3xy + y^2

2.(4c+2) (2c+3)=8c^2+12c+4c+6
8c^2 + 16c + 6
