Find the exact solution of x 3x^2+7=28

The exact solution of is or 2.64575

Solution:

Given, quadratic equation is

We have to find the exact solution for the variable x in the above given equation.

Now, let us solve the given equation to find the solution of the x

So, take the given equation,

On moving “7” from left side to right hand side we get,

On cancelling “3” on both sides, we get

Taking square root on both sides,

x = 2.64575

Hence, the exact solution for the x is or 2.64575
