so let's group and then factor ab+2a+3b+6= (ab+2a)+(3b+6)= a(b+2)+3(b+2)= (a+3)(b+2) and that is our final answer! Doctor Chuck

3a + 2a = 5a
The answer is 2a because of the two a's equal 2a
2a+2b+3a+3b+a+b= 6a+6b 2a+3a+a=6a 2b+3b+b=6b
No. 2a is one thing, 3b is another. If you add them together, they become 2a + 3b. 5ab indicates that multiplication has taken place. 5 times a times b = 5ab
To factor this particular expression, just look to see what factors both values share. In this case, 2 is the only factor shared. Using the distributive method, factoring out 2 works like this: a2 - c2 (usually written 2a - 2c) = 2 * (a-c) So the factors are 2 and (a-c).
