Question

Kurang kanlah
b 2(3p-4q) dari (5p+q)
c (3a-b-c) dari (4a+3b+2c)
d (3a²-a-3) dari (-6a²+9a+5)

Answer 1

A. 5p+q - 6p-8q = -p-7q
B. 4a+3b+2c - 3a-b-c = -a+2b-2c

Answer 2

B. 2(3p-4q) dari (5p+q)
= (5p+q) - 2(3p-4q)
= 5p+q-6p+8q
= 5p-6p+q+8q
= -p+9q

c. (3a-b-c) dari (4a+3b+2c)
= (4a+3b+2c) - (3a-b-c)
= 4a+3b+2c-3a-b-c
= 4a-3a+3b-b+2c-c
= a+2b+c

d. (3a²-a-3) dari (-6a²+9a+5)
= (-6a²+9a+5) - (3a²-a-3)
= -6a²+9a+5-3a²-a-3
= -6a²-3a²+9a-a+5-3
= -9a²+8a+2
Semoga membantu:)
