tolong buat besok nih

Saya coba bantu jawab yah !

Penyelesaian :
--------------------

a. 7a - 10a
= (7 - 10)a
= -3a

b. -4x + 12x
= (-4 + 12)x
= 8x

c. -15p + 9p - 18p
= -15p - 9p
= -24p

d. 6y² - 8y + y² - 2y
= 6y² + y² - 8y - 2y
= 7y² - 10y

Semoga bisa membantu

a)
7a - 10a
= (7 - 10)a
= -3a

b)
-4x + 12x
= (-4 + 12)x
= 8x

c)
-15p + 9p - 18p
= (-15 + 9 - 18)p
= (-6 - 18)p
= -24p

d)
6y² - 8y + y² - 2y
= 6y² + y² - 8y - 2y
= (6 + 1)y² - (8 + 2)y
= 7y² - 10y
= y(7y - 10)
