First we need to define what a like term is:
Like term meaning:
Terms whose variables (such as x or y) with any exponents (such as the 2 in x2) are the same. Examples: 7x and 2x are like terms because they are both "x".
Answer (for question 1):
For step one, you would just have to expand the brackets. The number of times multiplication would be used is 3 times. If you are confused, I attached a diagram in my ‘side notes’ section.
Answer (for question 2):
-5x squared and -12x squared are like terms because they both end in x squared.
Answer (for question 3):
There are no more like-terms.
Hope this helps!

Side notes:
2(3x)=1(4x-1)
6x=4x-1
Subtract 4x from each side
2x=-1
Divide each side to get x=-1/2
Your answer would be -1/2
Answer:
Step-by-step explanation:
Solving for x means you have to factor. First factor out the GCF of 2 to get:
and now we'll factor using the regular old method of ac and then factoring by grouping. In our polynomial, a = 3, b = 1, c = -6. Therefore, a times c is 3 * -6 which is -18. We need some combinations of the factors of 18 that will add to give us 1, the b term in the middle. The factors of 18 are:
1, 18
2, 9
3, 6 and that's it. Hm...it seems that won't work, so let's throw this into the quadratic formula, going back to the original and a = 6, b = 2 and c = -12:
and
and
and
and
which finally simplifies to
No wonder that didn't factor using the traditional method of factoring! We could have found that out by finding first the value of the discriminant, but oh well!
The answer is 6 when u are working with a negative a positive number subtracts
30 is the answer
