When we add 5a2b+6ab+7bc+54 to 14ab+8bc+16, we will get:
b + 20ab + 7bc + 70
b + 6ab + 7bc + 8ac + 70
b + 16ab + 7bc + 8ac + 70
b + 20ab + 7bc + 8ac + 70
5a2b+6ab+7bc+54 + 14ab+16+8bc
=5a2b+(6ab+14ab)+(7bc+8bc)+(54+16) =5a2b+20ab+15bc+70
When we add 5a2b+6ab+7bc+54 with 14ab+8ac+16, we will get:
The coefficient of b in −5a2b8c is:
