Answer:
c^2 +17c -5
Step-by-step explanation:
I like to line them up vertically
2c^2 +7c - 1
- (c^2 -10c+4)
----------------------
Distribute the minus sign
2c^2 +7c - 1
- c^2 +10c-4
----------------------
c^2 +17c -5
234 - 3 = 231
231 : 3 = 77
77 + 1 =78
78 + 1 = 79
------------------------
77 78 79
77+78+79= 234
