Question

factorise b^2+13b-14​

Answer 1

hi mate,

solution: Factoring b²+13b-14

b² - 1b + 14b - 14

Step-1 : Add up the first 2 terms, pulling out like factors :

b • (b-1)

Add up the last 2 terms, pulling out common factors :

14 • (b-1)

Step-2: Add up the four terms of step 1:

(b+14) • (b-1)

Which is the desired factorization

Final result :

(b + 14) • (b - 1)

i hope it helps you.

Answer 2

Answer:

b^2+13b-14=0

b^2-b+14b-14=0

b(b-1)14(b-1)=0

(b-1)(b+14)=0

b=1(or)-14
