[tex](8 + 2x).(5x - 7)[/tex]
[tex]8(5x - 7) + 2x(5x - 7)[/tex]
[tex]40x - 56 + 10x {}^{2} - 14x[/tex]
[tex]26x - 56 + 10x {}^{2} [/tex]
[tex]10x {}^{2} + 26x - 56[/tex]
Jawaban:
10x² + 26x - 56
Penjelasan dengan langkah-langkah:
= ( 8 + 2x ) . ( 5x - 7 )
= 8.5x - 8.7 + 2x.5x - 2x.7
= 40x - 56 + 10x² - 14x
= 10x² + 40x - 14x - 56
= 10x² + 26x - 56
