Answer:

Step-by-step explanation:

sqrt(2+x) > 6-2x

taking square on both sides

2+x  > 36-24x+4x^2

0 > 34-25x+4x^2

0 > (2x)2-2(2x)(25/4)+(25/4)^2 -(25/4)^2 +36         (by completing square)

49/16 > (2x-25/4)^2

taking square root

7/4 > 2x-25/4              ,     -7/4 < 2x-25/4

8 > 2x                          ,       9/2 < 2x

4 > x                            ,       9/4 < x
