Tentukan jumalah dari
a. 6p-5q-2r dan -8p+6q+9r
b. 8q²+4x-21 dan 6x²-14x+7
c. 2(3a+5b+3) dan 4(2b-3a+6)
d. 4(2x²-3x+5) dan 3(4x²+2x-7)

MathSolver74 A) 6p - 8p - 5q + 6q - 2r + 9r
= - 2p + q + 7r

b) 8x² + 6x² + 4x - 14x - 21 + 7
= 14x² - 10x - 14

c) 6a - 12a + 10b + 8b + 6 + 24
= - 6a + 18b + 30

d) 8x² + 12x² - 12x + 6x + 20 - 21
= 20x² - 6x - 1
