Question

What is the solution set of 4x 2 - 36 = 0?

Answer 1

4x2-36=0
+36 +36
4x2=36
Divide by 4
X2=9
Square root of x2 is x and the square root of 9 is 3
X=3

Answer 2

The solution set of equation
`4x^2-36=0` is 3 and -3.

Explanation:

Given: Equation
`4x^2-36=0`

We have to find the solution set of equation
`4x^2-36=0`

Consider the given equation
`4x^2-36=0`

Adding 36 both side, we get,

`4x^2-36+36=36`

Simplify, we get,

`4x^2=36`

Divide both side by 4, we get,

`x^2=9`

Taking square root both side, we have,

`x=√(9)`

Simplify, we get,

`x=\pm 3`

Thus, The solution set of equation
`4x^2-36=0` is 3 and -3.
