-2(x+3y+1)x(x+2y-4)(2x-3) (3x+1)(x+2 (2x-1)
Jawaban:
# Soal (1)
-2(x + 3y + 1)
= (-2 × x) + (-2 × 3y) + (-2 × 1)
= -2x – 6y – 2
# Soal (2)
x(x + 2y – 4)
= (x × x) + (x × 2y) – (x × 4)
= x² + 2xy – 4x
# Soal (3)
(2x – 3)(3x + 1)
= 2x(3x + 1) – 3(3x + 1)
= 6x² + 2x – 9x – 3
= 6x² – 7x – 3
# Soal (4)
(x + 2)(2x – 1)
= x(2x – 1) + 2(2x – 1)
= 2x² – x + 4x – 2
= 2x² + 3x – 2
