\huge\textsf{Hey there!}


\large\textsf{(x - 2)(x - 1)}


\large\textsf{DISTRIBUTE}


\large\textsf{x(x) + x(-1) - 2(x) -2(-1)}


\large\textsf{x(x) = }\mathsf{\bf x^2}


\large\textsf{x(-1) = -1(x) = \bf -1x}


\large\textsf{-2(x) = \bf -2x}


\large\textsf{-2(-1) = \bf 2}


\mathsf{= \bf x^2 - 1x - 2x + 2}


\large\textsf{COMBINE the LIKE TERMS}


\mathsf{(-1x - 2x)}


\mathsf{= \bf -3x}


\large\textsf{SOLVE for the ANSWER:}


\mathsf{x^2 - 3x + 2}


\boxed{\boxed{\large\text{Answer: }\mathsf{\bf x^2 - 3x + 2}}}\huge\checkmark
