Question

factor trinomial

14y^2-12y+3

Answer 1

Again, the first step is to look for a common factor. There isn't one.

Answer 2

Second step, multiply ac. What do you get?

Answer 3

why isn;t there one?

Answer 4

14, -12, and 3 are not all divisible by any number other than 1.

Answer 5

ok

Answer 6

So there is no common factor that can be factored out of all three terms.

Answer 7

Now we move to the next step. Multiply ac

Answer 8

42

Answer 9

Good. Now what two factors of 42 add to -12?

Answer 10

Since 42 is positive, and -12 is negative, both factors have to be negative. What two numbers multiply to +42 and add to -12?

Answer 11

It's not factorable using real numbers.

14y^2-12y+3

2y(7y - 6) + 3

Answer 12

cant figure it out

Answer 13

-42 * (-1) = 42, but -42 + (-1) = -43, not -12
-21 * (-2) = 42, but -21 + (-2) = -23, not -12
-14 * (-3) = 42, but -14 + (-3) = -17, not -12
-7 * (-6) = 42, but -7 + (-6) = -13, not -12
There are no two factors of 42 that add up to -12, so this trinomial is not factorable.

Answer 14

i knew it!! thanks
