Use the distributive property to expand the expression:

[tex]\[
(x-9)(x-1)
\][/tex]

[tex]\[
x^2 + \square x + \square
\][/tex]


Sagot :

To expand the expression [tex]\((x-9)(x-1)\)[/tex] using the distributive property, also known as the FOIL method, follow these steps:

1. Multiply the first terms: [tex]\( x \cdot x = x^2 \)[/tex].
2. Multiply the outer terms: [tex]\( x \cdot (-1) = -x \)[/tex].
3. Multiply the inner terms: [tex]\( -9 \cdot x = -9x \)[/tex].
4. Multiply the last terms: [tex]\( -9 \cdot (-1) = 9 \)[/tex].

Now, combine all these products:

[tex]\[ x^2 + (-x) + (-9x) + 9 \][/tex]

Next, combine the like terms:

[tex]\[ x^2 + (-x - 9x) + 9 = x^2 - 10x + 9 \][/tex]

So, when we use the distributive property to expand [tex]\((x-9)(x-1)\)[/tex], we get:

[tex]\[ x^2 + (-10)x + 9 \][/tex]

Thus, the complete expanded expression is:

[tex]\[ x^2 - 10x + 9 \][/tex]
