Question

Factorise 6b²+3b+8b+5​

Answer 1

( 6b + 5 ) ( b + 1 )

Explanation:

6b² + 3b + 8b + 5​

6b²+ 11b + 5

6b²+ 5b + 6b + 5

( 6b + 5 ) ( b + 1 )

Answer 2

(6b + 5)(b + 1).

Explanation:

6b² + 3b + 8b + 5​

= 6b^2 + 11b + 5

= 6b^2 + 6b + 5b + 5

= 6b(b + 1) + 5(b + 1) b + 1 is common so:

= (6b + 5)(b + 1)
