Question

Factorise the following 8b² - 22b + 15
Please tell the correct answer with explanation. I will mark that person as the brianliest ​

Answer 1

Solution :

8b² - 22b + 15 = 0

8b² - 12b - 10b + 15 = 0

4b(2b - 3) - 5(2b - 3) = 0

(4b - 5)(2b - 3) = 0

4b - 5 = 0

$\rightsquigarrow$ b = 5/4

2b - 3 = 0

$\rightsquigarrow$ b = 3/2
