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
(3 - i)(3 + i)
10a + 15 = 5 (2a + 3)
2a3-16a2+30a Factor out 2a: 2a(a2-8a+15) (2a)(a-5)(a-3) This is the most factored form of this expression.
