Question

8 < x(7 – x)

Answer 1

are you supposed to solve for \(x\)?

Answer 2

yes

Answer 3

this is way harder than the others
first multiply out on the right to get \[8<7x-x^2\]

Answer 4

then add \(x^2\) and subtract \(7x\) to get \[x^2-7x+8<0\]

Answer 5

ok

Answer 6

is there a typo somewhere in the question? you have to solve this using the quadratic formula
are you sure it is not \[-8<x(x-7)\]?

Answer 7

I'm sure

Answer 8

are you just supposed to find some number that works? what does the question actually say?

Answer 9

They're two questions.
1. What is the solution of the inequality?
2. Solve for x
