X2 + x – 6 = 0
(points : 4)
{2, 3}
{6, –1}
{3, –2}
{2, –3}

              x² + x - 6 = 0
      x² + 3x - 2x - 6 = 0
x (x + 3) - 2 (x + 3) = 0
         (x + 3) (x - 2) = 0

Now,  Using zero product property, we have,

EITHER,

x + 3 = 0
      x = -3

OR,

x - 2 = 0
     x = 2

So, x is either -3 or 2

So, the answer is {2 , -3}

X2 + x - 6 = 0. Your answer should be {2, -3}. 

The answer would be c.8(2)=16-16=0 -8(2)=16-16=0
