Answer:
Step-by-step explanation:
6y^2-7y-3-2y^2+9y+7 (pretend that you're multiplying -1 to 2y^2-9y-7 which is why 9y and 7 are positive now).
Now you're able to simplify your problem, so...
6y^2-2y^2= 4y^2
-7y+9y= 2y
-3+7=4
4y^2+2y+4

Answer:23 And 24
Step-by-step explanation:
((37 - (−√(−24))) - (−√(37))) - 24 =
19.0827625 + 4.89897949 i
19.0827625
+ 4.89897949
23.98174199
