Y = x2 + 5x + 4

How do I factor

(x + 1) * (x + 4)

Step-by-step explanation:

y = x² + 5x + 4

First, you multiply the first coefficient by the third coefficient: 4

Then you find all the factors of 4:

Of all these factors, you must find the pair that adds to 5 (the second coefficient)

Those factors are:  1 and 4

Then you put those into (x+_) and multiply them together:

( x + 1 ) * ( x + 4 )

  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.

i think 1: 2
