Answer 1

\[^{x2} +4x + 4\ge 9\]

Answer 2

To mathteacher: Because 2 is divisible by 4.

Answer 3

subtract 9 from both sides:\[x ^{2}+4x -5 \ge 0\]this should now be solvable

Answer 4

hint: factor the above

Answer 5

x^2 +4x +4 >= 9 subtract 9 from both sides
x^2 +4x -5 >= 0 factor the polynomial on the left

Can you factor that polynomial?

Answer 6

thats where i got stuck at

Answer 7

Is it factoring polynomials in general or factoring this *specific* polynomial that gives you trouble?

Answer 8

in general
