2
as a trinomial in standard form.



Answer :

Answer:

  x² -24x +144

Step-by-step explanation:

You want the expanded form of (x -12)².

Distributive property

You can find the expanded form of the given square using the distributive property:

  (x -12)² = (x -12)(x -12) = x(x -12) -12(x -12)

  = x² -12x -12x +144

  = x² -24x +144

Additional comment

The square of a binomial is ...

  (a +b)² = a² +2ab +b²

For a=x and b=-12, this is ...

  (x -12)² = x² +2(x)(-12) +(-12)² = x² -24x +144

If you remember the general form of the square of a binomial, you can write down the answer.
