Multiply
(1-x)(9-8x)
the answer that I came up with is
(x-1)(x-8)
can some help me and if I am wrong help me to solve
now use FOIL for (x-1)(x-8)
(Broken Link Removed)
to get
x^2 - 9x + 8
LOL
now that was not supposed to happen
here is the real link

Can you divide using the foil effect
the answer I got then is
8x^2-17x-9
no, FOIL is an acronym used to multiply two binomials like you had.
(x-1)(x-8)
F -- multiply the "firsts" ---> (x)(x) = x^2
O -- multiply the 'outers' ---> (x)(-8) = -8x
I -- multiply the 'inners' ---> (-1)(x) = -x
L -- multiply the 'lasts' ---> (-1)(-8) = 8
so x^2 - 8x - x + 8
= x^2 - 9x + 8
I don't have a clue how you got your answer.
To multiply the expression (1-x)(9-8x), we can use the distributive property. This property states that for any three numbers a, b, and c, the product of a and the sum of b and c is equal to the sum of the products of a by each individual term in the sum.
In this case, we can apply the distributive property as follows:
(1-x)(9-8x) = 1(9-8x) - x(9-8x)
Now, let's multiply each term:
1(9-8x) = 9 - 8x
-x(9-8x) = -9x + 8x^2
Combine the two terms:
(1-x)(9-8x) = 9 - 8x - 9x + 8x^2
Simplify the expression:
9 - 8x - 9x + 8x^2 = 9 + (-8x - 9x) + 8x^2 = 9 - 17x + 8x^2
So, the correct answer is 9 - 17x + 8x^2. The expression (x-1)(x-8) is not equivalent to (1-x)(9-8x).
