whehe :v masih kosong itu kak​

Answer 1

Penjelasan dengan langkah-langkah:

f(x) = 77x² × 77x² - 67x²

f(x) = 5.929x⁴ – 67x²

f(x) = x²(5.929x² – 67)

f(2b + 2) =(2b + 2)²(5.929(2b + 2)² – 67)

f(2b + 2) =(4b² + 8b + 4)(5.929(4b² + 8b + 4) – 67)

f(2b + 2) =(4b² + 8b + 4)(23.716b² + 47.432b + 23.716 – 67)

f(2b + 2) =(4b² + 8b + 4)(23.716b² + 47.432b + 23.649)

f(2b + 2) = 94.864b⁴ + 189.728b³ + 94.596b² + 189.728b³ + 379.456b² + 94.596b + 94.864b² + 189.728b + 94.596

f(2b + 2) =94.864b⁴ + 379.456b³ + 568.916b² + 284.324b + 94.596
