It is the expression 3 + 2a.
(a - 6)(2a + 3)
19-3 in a verbal expression = 16
That verbal expression would read: 3(x+y)^2 + 5(2x -y) ^2 means 'squared' in the above example.
3b -1
(2a - 3)(3a - 4)
2
I guess you mean: 2a^2+6a Well in this case you take 2a out of the bracket and then you're left with a+3 inside. 2a(a+3a)
+3
Well, honey, the answer to "3 plus 2a equals" is simply "3 + 2a." I mean, come on now, it's right there in the question! Just leave it as is unless you want to simplify it further, but that's as far as I'm willing to go with math today, darling.
(3 - i)(3 + i)
10a + 15 = 5 (2a + 3)
