Question

The sum of roots of the equation x^2-6x+2=0 is?

Answer 1

Answer:

sum of roots of any quadratic equation is

=-b/a

=-(-6)/1

=(-6)

Answer 2

Answer:

6

Step-by-step explanation:

x²-6x+2=0

Using quadratic formula,

$x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a}\\ when ax^2 + bx + c = 0\\where\\a, b, c = constants, where a ≠ 0\\x = the unknown$

we get, root x

$x=\frac{6 \pm \sqrt{36-(4X2)}}{2}$

$x=3 \pm \sqrt{7}$so, the 2 roots are

$3+\sqrt3$ and $3-\sqrt3$

sum of both the roots gives 6 as the answer.
