Question

Factor the trinomial.
3(a + b)2 + 5(a + b) − 2

Answer 1

am I able to use the quadratic equation with these values??

Answer 2

just for sake of simplicity let x=a+b
so now u have quadratic equation:
3x^2+5x-2
now u can use quad eq. .....

Answer 3

in the end u can resubstitute back x as
x=a+b

Answer 4

alright, so A+B= \[(-5\pm7)/6\] where do I go from here?

Answer 5

my two answers lead to -2 and 1/3. How do I present my results in an answer form?

Answer 6

if a is the root
x-a is the factor
make sense?

Answer 7

so if x=1/3
factor will be
x-1/3
or (3x-1)
so (3a+3b-1)
can u find other factor???

Answer 8

I'm failing to understand the concept. I appreciate that you're not solving the problem for me, but what did you do to transform your x-1/3 to (3x-1)?

Answer 9

x-1/3 = (3x-1)/3 right?
since f(x)=0 was your quadratic equation, that /3 will not have any effect.

Answer 10

the other factor would be x+2
(a+b+2)
