Question

factorise: b²+22b-48​

Answer 1

Answer:

b² + 22b - 48

= b² + b ( 24 - 2 ) - 48

= b² + 24b - 2b - 48

= b ( b + 24 ) - 2 ( b + 24 )

= ( b + 24 ) ( b - 2 )

Answer 2

Answer:

(b-2)(b+24)

Step-by-step explanation:

${b}^{2} + 22b - 48 \\ {b}^{2} + 24b - 2b - 48 \\ b(b + 24) - 2(b + 24) \\ (b - 2)(b + 24)$
