Lim x² + 20x - 3x
x → 6

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

= 2.000 - 900

= 1.100

Lim x² + 20x - 3x

= 6² + 20(6) - 3(6)

= ( 6 × 6 ) + 20(6) - 3(6)

= 36 + ( 20 × 6 ) - ( 3 × 6 )

= 36 + 120 - 18

= 156 - 18

= 138
