Step-by-step explanation:
simplify-3(x-3) you should get -3x+9.
then use foil to get (-3x+9)(x+7)
you multiply -3x with (x+7) and tou should get (-3x^2-21x)
then multiply 9 with (x+7) and you should get (9x+63)
now you should have the numbers: -3x^2, -21x, 9x, and 63.
combine like terms: add 9x to -21x and tou will get -12x.
Now place the numbers in the correct order: variables with exponents, then nirmal variables, then non variables
