sederhanakan bentuk aljabar berikut a.7a-10a= b.–4x+12x= c.-15p+9p–18p= d.6y²–8y+y²2y= pakai cara

Mapel : Matematika
Kelas : VII SMP
Bab : Aljabar dasar

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

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

————————————————
-15p + 9p - 18p
= (-15 + 9 - 18)p
= -24p

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

A. 7a - 10a = -3a
B. -4x + 12x = 8x
C. -15p + 9p - 18p = -6p - 18p = -24p
D. 6y²– 8y + y² + 2y = 6y^2 + y^2 - 8y + 2y = 7y^2 - 8y + 2y = 7y^2 - 6 y

semoga membantu^^
