Question

Jabarkan menjadi suku-sukunya!
a. 4(2m - 3n)
b. -4p(2p - 5q)
c. 5x(-3x + y - 2)

Answer 1

A. 4(2m - 3n) = 8m - 12n
b. -4p(2p - 5q) = -8p² + 20pq
c. 5x(-3x + y - 2) = -15x² + 5xy - 10x

semoga membantu ya.. :)

Answer 2

a. 4(2m - 3n)
= (4 × 2m) (4 × -3n)
= 8m - 12n

b. -4p(2p - 5q)
= (-4p × 2p) (-4p × -5q)
= -8p² + 20pq

c. 5x(-3x + y - 2)
= (5x × -3x) (5x × y) (5x × -2)
= -15x² + 5xy - 10x
