Let x = your number.
6x = x^2 - 27. Subtract 6x from each side.
0 = x^2 - 6x - 27. Factor
0 = (x-9) (x+3). Set each term equal to zero
(x+3) = 0. Subtract 3 from each side.
x = -3. This is the negative solution.
(x-9) = 0. Add 9 to each side.
x = 9. This is the positive solution.

Answer:
this is how you do it .
it doesn't have a end it just kept going
For 175 : 250 divide them both by 25 to get

<

25 goes into 175 > 7 times > 25 into 250 is 10 times! >

For the second one 16 : 40 just divide the top and bottom by 8 since 8 is a common factor of both which will give us

.
8 goes into 16, 2 times and 40, 5 times.
