Dear Forum I solved the following but I need help solving is using(sign charts- critical value method)I solved the inequality but I need help solving it using sign charts.

1.Solvex2 + 11x + 18 > 0using the Critical Value (Sign Chart) method.

what I came up with was:

x^(2)+11x+18>0

Factor the trinomial x^(2)+11x+18.

(x+9)(x+2)>0

Set each of the factors of the left-hand side of the inequality equal to 0 to find the critical points.

x+9=0_x+2=0

Since 9 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 9 from both sides.

x=-9_x+2=0

Set each of the factors of the left-hand side of the inequality equal to 0 to find the critical points.

x=-9_x+2=0

Since 2 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 2 from both sides.

x=-9_x=-2

Since this is a 'greater than 0' inequality, all intervals that make the expression positive are part of the solution.

x<-9 or x>-2
