If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
(m + 6)(m + 1)
18m^2 - 12m + 2 = 2(9m^2 - 6m + 1) you can apply the formula (a - b)^2 = (a^2 - 2ab + b^2) or if you don't remmember it, continue to work: = 2(9m^2 - 3m - 3m + 1) = 2[(9m^2 - 3m) - (3m - 1)] = 2[3m(3m - 1) - (3m - 1)] = 2[(3m - 1)(3m - 1)] = 2(3m - 1)^2
8(3m - 1)(m - 1)
1
When simplified it is just: 1
-3m + 8 - 7 = -3m + 1
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
(m + 6)(m + 1)
-3m = 5m+8 -3m-5m = 8 -8m = 8 m = -1
2m + 1
18m^2 - 12m + 2 = 2(9m^2 - 6m + 1) you can apply the formula (a - b)^2 = (a^2 - 2ab + b^2) or if you don't remmember it, continue to work: = 2(9m^2 - 3m - 3m + 1) = 2[(9m^2 - 3m) - (3m - 1)] = 2[3m(3m - 1) - (3m - 1)] = 2[(3m - 1)(3m - 1)] = 2(3m - 1)^2
(m + 5)(3m - 1)
8(3m - 1)(m - 1)
1
It is: x-1+4+7x-3 = 8x simplified
It is: 7a+1 when simplified
