Penjelasan dengan langkah-langkah:
a. 6mn + 3mn = 9mn
b. 16x + 3 + 3x + 4
= 16x + 3x + 3 + 4
= 19x + 7
c. -x - y + x - 3
= -x + x - y - 3
= -y - 3
d. 2p - 3p² + 2q - 5q² + 3p
= -3p² - 5q² + 2p + 3p + 2q
= -3p² - 5q² + 5p + 2q
e. 6m + 3[m² – n²] – 2m² + 3n²
= 6m + 3m² – 3n² – 2m² + 3n²
= 3m² - 2m² – 3n² + 3n² + 6m
= m² + 6m
.
b. 16x + 3 + 3x + 4 = 19x + 7
c. –x – y + x – 3 = -y - 3
d. 2p – 3p2 + 2q – 5q2 + 3p =
e. 6m + 3[m2 – n2] – 2m2 + 3n2 =
