Question

Can u help me step by step need to fill in the blanks

Answer 1

-18a+17b is the answer because you multiply by -1 to each

Answer 2

The minus sign outside of the parentheses can actually be represented with -1 instead.

this means that you must distribute (multiply) -1 by the numbers inside of the parentheses.

keep in mind that when you multiply the -1 by the 2nd number inside, and the operation is subtract, instead of 17b, it would be -17b.

-1 • 18a = -18a
-1 • -17b = -17b

the final answer would be -18a + 17b :)
