Question

1. Hasil dri (3x + 2)(x - 1)
2. (2p - 3q)(5p + 2q)
3. (8 - y)(y + 3)
4. (2y - 5)(y - 3)
5. (Y + 3)(y + 4)

Pake cara y :) makasih

Answer 1

1. 3x(x-1) + 2(x-1) = 3x^2 - 3x + 2x -2 = 3x ^2 - x -2
2. 2p( 5p+2q) -3q(5p+2q) = 10p^2+ 4pq -15pq - 6q^2 = 10p^2-11pq - 6q^2
3. 8(y+3)-y(y+3) =8y + 24-y^2-3y = 5y + 24-y^2 = y^2 -5y - 24
4. 2y(y-3)-5(y-3)= 2y^2-6y-5y+15. = 2y^2-11y+15
5. y(y+4)+3(y+4) = y^2 + 4y+3y+12 = y^2 + 7y+12

Answer 2

1. (3x+2)(x-1)
3x2 - 3x + 2x -2
3x2 - x - 2
