Question

Write the sum of real roots of the equation x2 + |x| − 6 = 0.

Solution

The given quadric equation is x2 + |x| − 6 = 0.

Here,  a =1,b = ±1 and, c = -6

As we know that `D = b^2 - 4ac`

Putting the value of a =1,b = ±1 and, c = -6

` = (±1)^2 - 4 xx 1 xx -6`

= 1 + 24

 = 25

Since, D ≥ 0

Therefore, root of the given equation arereal and distinct.

Thus, sum of the roots be = 0. 

  Is there an error in this question or solution?
