anonymous · Answer

y = (3x+2)(2x-1) 
do you know how to simplify it ? multiply the terms ?

anonymous · Answer

Yes

anonymous · Answer

ok what do you get after simplifying ?

anonymous · Answer

It's b

anonymous · Answer

what b?

anonymous · Answer

y=(3x+2)(2x-1) 
open the brackets what do you get ?

anonymous · Answer

I meant to say that the answer is D. It turns out to be 6.

anonymous · Answer

y = (3x+2)(2x-1)
y = 6x^2 +4x -3x - 2
y = 6x^2 +x -2

b is to coefficient of the 'x' 
so its not 6.

anonymous · Answer

I keep getting it wrong ! :(

anonymous · Answer

y = 6x^2 + x - 2

y = ax^2 +bx + c

so 
a = 6
b = 1
c = -2

.. b = 1.
