Answer 1

I AM PRICES I AM PRICELESS

Answer 2

Answer:

(3y-1) (4y+1)

Step-by-step explanation:

Q) Factorize 12y²-y-1

Here we can use the factorization method.

The product is -1 * 12 = -12

and Sum is -1

So we need to find factors of 12  that sum up to -1 and while multiplying it gives -12.

The factors of 12 are 1, 2, 3, 4, 6, and 12.

When we take -4 and 3, we get the sum as -1 and the product as -12.

Thus, it is satisfying the statement.

So by using the factorization method,

12y²-y-1

=> 12y² -4y + 3y -1

Now grouping,

=> 4y(3y - 1) + 1(3y - 1)

So therefore after factorization, we get (4y + 1) and (3y - 1)
