Question

11(m+1) (m+2) =38 (m+1)+9m solve by formula method​

Answer 1

Answer:

11(m+1) (m+2) =38(m+1) +9m

or, 11(m^2+m+2m+2) =38m+38+9m

or, 11m^2+33m+22=47m+38

or, 11m^2-14m-16=0

or, 11m^2-22m+8m-16=0

or, 11m(m-2) +8(m-2) =0

or, (m-2) (11m+8) =0

or, m-2=0

or, m=2

and, 11m+8=0

or, m=-8/11
