Quadratic formula method xsquare-2x=2​

Answer 1

Answer:

see the attachment. above

Answer 2

Answer:

Let us consider the quadratic equation:

ax^2 + bx +c = 0

We have Sridhar Acharya's formula for calculating the root of the equation as:

x = (-b +/- sqrt(b^2 - 4ac))/2a

Now replace a =1, b = 2, c = -2 to relate with your equation, we have:

x = (-2 +/- sqrt(4 - 4*1*(-2))/2 = (-1 +/- sqrt(3)) (Since sqrt(12) = 2*sqrt(3))

Step-by-step explanation: I hope it's helpful.
