Question

What is the value of the coefficient "b" when the quadratic equation y = (3x + 2)(2x − 1) is written in standard form?

Answer 1

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

Answer 2

Yes

Answer 3

ok what do you get after simplifying ?

Answer 4

It's b

Answer 5

what b?

Answer 6

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

Answer 7

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

Answer 8

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.

Answer 9

I keep getting it wrong ! :(

Answer 10

y = 6x^2 + x - 2

y = ax^2 +bx + c

so
a = 6
b = 1
c = -2

.. b = 1.

Answer 11

I wish it came easily to me :/
thanks..

Answer 12

no worries.. keep on practicing
i got it with hard work as well
