Question

LOTS OF POINTS Please help

Answer 1

#1. The correct answer is C. 5b²-b-2

#2. The correct answer is A. 4x-5

Explanation:

#1. (5b²-3b+2)+(2b-4), combine like terms. -----> 5b² doesn't have any like terms, so you would move onto -3b and 2b, -3+2= -1 or in other words, just b. Now move onto +2 and -4, 2+-4= -2. So, your answer would be 5b²-b-2.

#2. (6x-3)-(2x-2), also, combine like terms here. -------> 6x has a like term in the other set of parenthesis, 2x. So, you would subtract 6-2= 4, and you would now have 4x. Same thing with -3 and -2. -3-2= -5. So, now your answer would be 4x-5.

Hope this helped you understand!! (:

Answer 2

1. 5b^2-b-2 (so option 3)

2. 4x-1 (so option 2)

Explanation:

For the first one you need to just simplify the expression

For the second one you need to combine like terms
