Answer 3

Here come all the explanations!

Answer 4

LOL..... Explanations should come first.....

Answer 5

ok

Answer 6

Question #1

(5x2 + 3x + 4) − (2x2 − 6x + 3)

For this problem all u have to do is times a -1 by the right half of the expression

5x^2+3x+4-2x^2-6x+3

simplifies to: 3x^2+9x+1

value of b=9

Question #2

same thing as problem one just multiply by a negative 1 since thats what is in front of the parenthesis

Question #3

Just add them together

(3x - 2)+(x^2-5)+(2x+7)

isnt this really just

(3x - 2)+1*(x^2-5)+1*(2x+7)

so this simplifies to: x^2 + 5x

Question #4

(4x − 6) − (5x + 1)

this is the same idea as problem 1 and 2

(4x − 6) − 1*(5x + 1)

times by a negative 1

4x-6-5x-1

Answer: -x-7

Question #5

(x + 6y) - (3x − 10y)

this is the same ideas as problem 1,2, and 4

(x + 6y) -1* (3x − 10y)

Question #6

(3x − 5) + (3x + 6)

3x-5+3x+6

combine like terms....

Answer: 6x+1
