Question

Sum of the roots of the equation x2-6x+2 = 0 is
(a) –6 (b)-2
(d) 6
(c) 2​

Answer 1

Step-by-step explanation:

If α and β are the roots of a quadratic equation x2 – 6x + 2 = 0 then, Sum of roots (α + β) = -b/a = -(-6)/1 = 6

Answer 2

Given:

Quadratic equation = x²-6x+2 = 0

To find:

The sum of the roots of the given equation.

Solution:

Let us consider a quadratic equation of the form:

ax²+bx + c= 0

Then the sum of the roots of the given equation will be:

= -b/a

Thus, in the given equation, the sum of its roots will be:

= - (-6) /1

On simplifying, we get the sum of the roots of the equation as:

= 6

Thus, the sum of the roots of the given equation will be 6.

Option D is correct.
