Question

Factorize (m - 1) (1 -m) + m + 109​

Answer 1

Answer:

m= -9,12

Step-by-step explanation:

(m-1)(1-m) +m +109=0

m- m²-1+m+m+109=0

-m²+3m+108=0

-(m²-3m-108)=0

m²-3m-108=0

m²-12m+9m-108=0

m(m-12) +9(m-12)=0

(m+9)(m-12)=0

m= -9 , 12

Answer 2

Answer:

m = 12 or -9

Step-by-step explanation:

( m - 1 ) ( 1 - m ) + m + 109 = 0

=> m - m² - 1 + m + m + 109 = 0

=> m² - 3m - 108 = 0

=> m² - 12m + 9m - 108 = 0

=> m ( m - 12 ) + 9 ( m - 12 ) = 0

=> ( m - 12 ) ( m + 9 ) = 0

=> m = 12 or m = -9 ANS
