Draw the graph of

Answer :

We are given y = x2 + x – 12


So taking the values of X in between –3 and 3 we can find various value of y and put them in graph



Again we are given


x2 + 2x + 2 = 0


we can write the above expression as


x2 + x + x–14–12 = 0


x2 + x–12 + x + 14 = 0


y + x + 14 = 0 (as x2 – x – 6 = 0 )


y = –x–14


Now we can draw another pair of value using the above data



Now we can draw the graph and the intersection of the two lines will give the roots for the equation.



From the above graph it’s clear that the line doesn’t intersect each other so there is no solution.
