Question

Given 1.2x^2−2.4=0. Find the roots of the equation.

Answer 1

`x=√(2)`,
`x=- √(2)`

Explanation:

Given:

`1.2x^2-2.4=0`

We need to find roots of the equation.

First we will solve the above equation and then will remove the root for the same.

`1.2x^2-2.4=0\\1.2x^2=2.4\\x^2=(2.4)/(1.2)=2\\`

Now to find the roots we need to square root on both side.

`√(x^2)=√(2)\\`

square and square root gets cancelled we get.

`x= √(2)`,
`x= - √(2)`
