As we can find that

-8² is -8 x -8  and -7² is -7 x -7

It has the same meaning with rules of positive and negative numbers operation in math :

  • If a negative value timed/divided by a negative value, the result is a positive value.
  • if a positive value timed/divided by a negative value or vice versa, the result is a negative value.

Y= (x-9) (x+3)
juin [17]

Answer:

y = x² − 6x − 27

Step-by-step explanation:

To distribute, you can use something called FOIL.  It stands for First, Outer, Inner, Last.

First, multiply the First term in each factor.

x · x = x²

Now multiply the Outer terms in each factor.

x · 3 = 3x

Next multiply the Inner terms in each factor.

-9 · x = -9x

Finally, multiply the Last terms in each factor.

-9 · 3 = -27

Add them all up:

x² + 3x − 9x − 27

x² − 6x − 27
