Question 211885
{{{(x-3)^2}}}
To multiply this expand the expression.  As the problem is asking you to square:
(x-3)*(x-3) 
Now use the FOIL method to find the product.
FOIL is an acronym for First, Outer, Inner, Last
Multiply the first term of each expression
x * x = x^2
Next, multiply the two outer terms:
x * -3 = -3x
Then multiply the inner terms:
x * -3 = -3x
Finally, the last terms
-3 * -3 = 9

Add all of terms together:
{{{x^2 + (-3x) + (-3x) +9}}}
Combine like terms:
{{{x^2 - 6x + 9}}}
This is your answer
