Q. math~

Hasil perkalian dari ( 2x - 5 ) ( 3x + 1 ) adalah ...​

⏩ Penyelesaian soal:

Diketahui:

  • ( 2x - 5 ) ( 3x + 1 )

Ditanya:

  • Hasil

Jawab:

= ( 2x - 5 ) ( 3x + 1 )

= ( 2x × 3x ) + ( -5 × 3x ) + ( 2x × 1 ) + ( -5 × 1 )

= 6x² + ( -15 )x + 2x + ( -5 )

= 6x² - 15x + 2x - 5

= 6x² - 13x - 5

Mohon dikoreksi

= (2x - 5)(3x + 1)

= (2x. 3x) + (2x. 1) + (-5.3x) + (-5.1)

= 6x² + 2x - 15x - 5

= 6x² - 13x - 5
