Answer:
(x-7) (x-8)
Step-by-step explanation:
Break the expression into groups:
= x(x-7) -8(x-7)
Factor out x from:
x^2-7x x(x-7)
Factor out -8 from -8x+56:
-8(x-7)
=x\left(x-7\right)-8\left(x-7\right)

Answer:
21/99 or 7/33
Step-by-step explanation:
x = 0.212121
Then we multiple the decimal and x by hundred.
100x = 21.212121
Then we subtract the 21.212121 by 0.212121.
100x = 21.212121 - 0.212121
But when you are subtracting 100x, you need to subtract 100x by x because in the first step it said x = 0.212121.
100x - x = 21.212121 - 0.212121
You will have at the end is
99x = 21
Divide 99 on both side and you left with
21/99 or 7/33 simplified version
