Expand the brackets: (2m-3)(m+1)

To expand the brackets we consider each bracket separately, (2m-3) which is multiplied by (m+1). Consider first the first identity in each bracket:2m x m = 2m2Then consider the first identity and the last of the second bracket. 2m x 1 = 2mLogically, move on to the second identity of the first bracket:-3 x m = -3m-3 x 1 = -3To conclude, put these terms together to give:2m2 + 2m - 3m -3Simplify:2m2 - m - 3
