(7m+6) (6-7m)=36-m (m+1)

Question

(7m+6) (6-7m)=36-m (m+1)

Answer 1

(7m+6) (6-7m)=36-m (m+1)

7m(6-7m)+6(6-7m) = 36 - m(m+1)

42m-49m² + 36 - 42m = 36 - m²-m

-49m²+m²+m=0

-48m²+m = 0

m(-48m + 1) =0

m = 0 или -48m + 1 = 0

 m= 0  или -48m = -1

                       m = 1/48

Ответ: m∈{0; 1/48}
