Penjelasan dengan langkah-langkah:
f (×) = 35 × × - 5 × × + 75
f (8) = 35(8) × -5 × 8 + 75
= 280 × -5 × 8 + 75
= -1.400 × 8 + 75
= -11.200 + 75
= -11.125

بِسْـــمِ اللَّهِ الرَّحْمَــنِ الرَّحِيْمِ
f(x) = 35xx - 5xx + 75
= 35x² - 5x² + 75
= 30x² + 75
f(8) = 30(8)² + 75
= 30 × 64 + 75
= 1.920 + 75
= 1.995
وَاللَّهُ عَالَمُ بِاالصَّوَافَ
