Find the product of the following expression (x-15) (x-3)

x²-18x+45

Step-by-step explanation:

(x-15)(x-3)

Product of the first terms is x² [x times x]          F

Product of the outer term is -3x  [x times -3]     O

Product of the inner term is -15x [-15 times x]    I

Product of the last term is 45 [-15 x -3]               L

Combine like terms and you'll get x²-18x+45

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
