try -8 or -1 as the solution (-8) squared + 9(-8) + 14 = 0 (-1) squared + 9(-1) + 14 64 -72 + 14 = 0 1 - 9 + 14 = 0 -8 + 14 > 0 -8 + 14 = 0 6 > 0 TRUE 6 > 0 TRUE it means that the solution set are the numbers lesser than -7 like -8 up to negative infinity and greater than -2 like -1 up to positive infinity

{ x | x -7>x>-2 } or { x | x < -7 or x > -2 }

(x | x means for all the values of x such that x is lesser than -7 but greater than -2)

note: -7 and -2 are not included at the solution set since the sign is not greater than or equal to, it is included if it is signed like greater than or equal to.
