Question

What is the expression obtained when the sum of 2a−16abc−45 and 2a+7abc+11 is subtracted from 6a+6abc−30?

Answer 1

Answer: see explain

Step-by-step explanation:6a + 6abc -30 4a - 9abc -34 is the sumsubtract to get 2a+15abc +4

Answer 2

Explanation:

Add the first 2 trinomials

2a - 16abc - 45 + 2a + 7abc + 11

2a + 2a - 16abc + 7abc - 45 + 11 Combine like terms

4a - 9abc + 56

Now you want to subtract this answer from the third trinomial.

6a + 6abc - 30 - (4a - 9abc +56) Remove the brackets.

6a + 6abc - 30 - 4a + 9abc - 56 Rearrange so like terms are together

6a - 4a + 6abc + 9abc - 40 - 56 Combine

2a + 15abc - 106
