+1932 Solve the inequality x(x+6)>16−5x+33. Write your answer in interval notation.
+36 Hint:
Expanded, you an get
x2+6x>49−5x which simplfies into
x2+11x−49>0
Which can be factored - You can then draw a graph on a numberline where the 2 roots of the quadratic are points on a parabola, and find the ranges on the numberline for which the Y value of the parabola is positive.
Sorry, I don't know how to draw the graph on web2.0calc.
