Jawaban:
P(x) = 3x³ + 2x² - 5x - 6
P(2) = 3(2)³ + 2(2)² - 5(2) - 6
P(2) = 3(2³) + 2(2²) - 10 - 6
P(2) = 3(8) + 2(4) - 10 - 6
P(2) = 24 + 8 - 10 - 6
P(2) = 32 - 10 - 6
P(2) = 22 - 6
P(2) = 16

p(x) = 3x³ + 2x² - 5x - 6
p(2) = 3(2)³ + 2(2)² - 5(2) - 6
p(2) = 3(2 × 2 × 2) + 2(2 × 2) - (5 × 2) - 6
p(2) = 3(4 × 2) + 2(2 × 2) - (5 × 2) - 6
p(2) = 3(8) + 2(4) - 10 - 6
p(2) = (3 × 8) + (2 × 4) - 10 - 6
p(2) = 24 + 8 - 10 - 6
p(2) = 32 - 10 - 6
p(2) = 22 - 6
p(2) = 16
