40² + 20² - 30²
= (40×40) + (20×20) - (30×30)
= (1.600) + (400) - (900)
= 2.000 - 900
= 1.100

Lim x² + 20x - 3x
x → 6
x² + 20x - 3x
= 6² + 20(6) - 3(6)
= 36 + 120 - 18
= 156 - 18
= 138
Penjelasan dengan langkah-langkah:
= ( 40 × 40 ) + ( 20 × 20 ) - ( 30 × 30 )
= 1.600 + 400 - 900
= ( 6 × 6 ) + 20(6) - 3(6)
= 36 + ( 20 × 6 ) - ( 3 × 6 )
