Question

Factor and explain:
34. 8a+12b

35. 18x+6y+12

36. 3+12b+36a

37. 8a+4+12c

Answer 1

34.
8a+12b
=12(2.9+b)

You could now try the rest and post your results for checking.

Answer 2

37. The only common factor is 4.
8a+4+12c = 4(2a + 3c + 1)

The others are similar. Try them yourself.

Answer 3

34. 34.8b

Answer 4

34. 4(2a+3c+1)
35. 3(6x+2y+4)
36. 3(1+4b+12a)
37. 2(4a+6c+2)

Answer 5

Sorry, my #34 is not correct. I remember seeing the expression from another question. I have probably put it in the wrong response.

#34 should be
8a+12b
=4(2a+3b)
I do not know from where the "+1" in your response came.

#35
you have missed out another factor of 2.

#36 basically correct, although I prefer to order the terms in alphabetical order of the variables, like:
3(12a+4b+1)

#37
Factorization not complete.

Give it another try. You're getting there.
