Question

1.sederhanakan bentuk aljabar berikut.
a.5y-10y+13y
b.17a2+3a+11a2
c.6pq+5p2-8pq-p2+pq
d.8(a+2b)-12(2a-b)

Answer 1

A.18y
b.28a2+3a
c.-pq+3p2
d.8a+16b-24a+12b
=-16a+28b

Answer 2

a.5y-10y+13y = (5-10+13)y = 8y
b.17a²+3a+11a² = (17+11)a² + 3a = 28a² + 3a
c.6pq+5p²-8pq-p²+pq = (5-1)p² + (6-8+1)pq = 4p² -1pq = 4p² - pq
d.8(a+2b)-12(2a-b) = 8a + 16b -24a + 12b = (8-24)a + (16+12)b = -16a + 28 b
