Penjelasan dengan langkah-langkah:

[tex]\displaystyle\lim_{x \to -2} {3x}^{2} - {6x}^{2} - 8x + 20[/tex]

[tex]\displaystyle\lim_{x \to -2} { - 3x}^{2} - 8x + 20[/tex]

[tex] \displaystyle \: \: \: \: \: \: = - 3( { - 2)}^{2} - 8( - 2) + 20[/tex]

[tex]\displaystyle \: \: \: \: \: \: = - 3(4) - ( - 16) + 20[/tex]

[tex]\displaystyle \: \: \: \: \: \: = - 12 + 16 + 20[/tex]

[tex]\displaystyle \: \: \: \: \: \: =16 - 12 + 20[/tex]

[tex]\displaystyle \: \: \: \: \: \: =4 + 20[/tex]

[tex]\displaystyle \: \: \: \: \: \: =24[/tex]
