Question

These two questions are confusing

Answer 1

So for number 3 first of, here is how to do it.

3(x+2)
3x+6 (Multiply them together)

2(x-3)
2x-6 (Multiply these two together as well)

Now lets add them together.

3x+6+2x-6
5x+0

Therefore: The correct answer is A

For number 4;

You are going to be factoring the common number out of the two, which in this case is 5x.

The correct answer is 5x(3x+7), therefore the answer is F

Hope this helped!

Answer 2

3. Your answer is A. 5x
To solve, you'd expand the brackets, so
3 × x = 3x
3 × 2 = 6
2 × x = 2x
2 × -3 = -6
And then combine the like terms to get 5x.

4. Your answer is F. 5x(3x + 7)
This is because if you multiply 5x by 3x you get 15x², and if you multiply 5x by 7 you get 35x, and those are the two terms.

I hope this helps!
