PLEASE HELP ME FACTOR THIS!!

  (k +2j)(4k -j)

Step-by-step explanation:

Multiply the first and last coefficients to find their product:

  (4)(-2) = -8

Factor this product until you find factors that have a sum of +7. Since you want a positive sum, it works well to start with small negative factors.

  -8 = -1×8 . . . . these have the desired sum: (-1) +(8) = +7

Now, rewrite the middle term using these factors:

  4k² -jk +8jk -2j²

Factor each pair of terms

  k(4k -j) +2j(4k -j)

Recognize these new terms have a common factor, and factor that out:

  (k +2j)(4k -j) . . . . . the factorization you're looking for

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
