In physics, albert einstein's famous formula for mass-energy equivalence defines an object's energy, measured in joules ( j ) , n terms of its mass, m, measured in kilograms (kg) and the speed of light, c, measured in meters per second (ms)left parenthesis, m, slash, s, right parenthesis. the formula is commonly written as e = mc2. rearrange the formula to solve for the speed of light (c)

Begin by dividing both sides by m

                   Take the square root of both sides.

           Evaluate  the right

-1   1/6.   you dont subtract the denominators

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
