______________________
Diketahui :
• p(x) = 2x² + 4x² - 3x + 2
Ditanya :
• p(5) = ...
______________________
p(x) = 2x² + 4x² - 3x + 2
p(5) = 2(5)³ + 4(5)² - 3(5) + 2
p(5) = 2(5 × 5 × 5) + 4(5 × 5) - (3 × 5) + 2
p(5) = 2(25 × 5) + 4(25) - 15 + 2
p(5) = 2(125) + 4(25) - 15 + 2
p(5) = (2 × 125) + (4 × 25) - 15 + 2
p(5) = 250 + 100 - 15 + 2
p(5) = 350 - 15 + 2
p(5) = 335 + 2
p(5) = 337
•••
Kesimpulan :
Maka, Nilai dari p(5) adalah 337✓

#Koreksi
[tex]p(x) = 2 {x}^{3} + 4 {x}^{2} - 3x + 2[/tex]
[tex]p(5) = 2 \times {(5)}^{3} + 4 \times {(5)}^{2} - 3 \times 5 + 2[/tex]
[tex]p(5) = 2 \times 125 + 4 \times 25 - 15 + 2[/tex]
[tex]p(5) = 250 + 100 - 15 + 2[/tex]
[tex]p(5) = 337[/tex]
