hello.i have to factor this expression.
3y^2-16y-12

i did my work and i got (y-4)(y+1)
is it right?

1. Damon

(3 y + 2)(y - 6)

2. HI

thank you!

3. Damon

You are welcome.

Sure, fooled around with factors of 12
3 and 4 did not work, 1 and 12 did not work, so tried 6 and 2

6. Damon

I wrote

(3 y - ) (y + )
and tried factors
soon saw needed
(3 y + ) (y - )

then fooled with 3 and 4 and then 6 and 2 until it worked

7. HI

i messed up on my math . i used -12 and 3. now i know why i messed up. thank you again.:)

No problem :)

Totally confused-learned this today and I don't get it-Please help Write the standard form of 9x^2 + 4y^2-72x+16y+124=0 I think the first step is to take the constant to right side so I have: 9x^2 + 4y^2-72x+16y=124 But then I'm lost!

We can rewrite the expression 16 + 8 as 8x(2+1). Notice that 8 is the greatest common factor of 16 and 8. Use this same method to rewrite the expression 24 + 36 as the product of the greatest common factor of 24 and 36 and the sum …
