SOLUTION: When I expand and simplify this equation (2k-3)(k-2), I get
= 2k2 - 4k - 3k + 6
= 2k2 - k + 6
but I am told the right answer is
2k2 - 7k + 6
Please help. I don`t understand.

Answer by JulietG(1812) (Show Source): You can put this solution on YOUR website!
(2k-3)(k-2)=
(2k*k)+ (-3*k) + (-4*k) + (-3*-2)
2k^2 -7k + 6
Do you see the error? You added 4k instead of subtracting it.
