Sir how do you multiply (2b-1) (-5) 🙏🙏

[@YvonneSerwa]

2b x -5= -10b
-1 x -5 = 5
Therefore -10b + 5

[@Dixonwithanx]

2b-1=2b then you multiply 2b x 5 to find your answer

[@LilianMpengamali]

Thank you

[@belindakatenta9771]

On finding the value of b, is it not -5 not 5 ?

[@littleprincess9835]

Not really, it's 5 and not -5

[@DeborahMate-uh6ce]

2b-1 first subtract then multiply by -5 the answer will be -5b
