Answer:
6y^2 -12y -4
Step-by-step explanation:
8y^2 -5y+7 - (2y^2 +7y+11)
Be very careful here, remember to multiply out the sign first before doing anything because most people find themselves making mistakes if they don't do so.
8y^2 -5y+7 - 2y^2 -7y-11
Now combine the like terms and simply, solve!
8y^2 -2y^2 -5y-7y +7-11
6y^2 -12y -4
