20(x + 3) - (x + 2)(x - 3)

After distributing 20 and multiplying (x + 2) and (x - 3) together:

20x + 60 - (x^2 - 3x + 2x - 6)

After combining like terms:

20x + 60 - (x^2 - x - 6)

After distributing the negative sign to the quantity (x^2 - x - 6):

20x + 60 - x^2 + x + 6

After combining like terms:

- x^2 + 21x + 66

Answer:

20(x + 3) - (x + 2)(x - 3) = - x^2 + 21x + 66
