Question

What are the solutions to the quadratic equation 4x2=64?

Answer 1

X=4 or X=-4 because 4(4)^2 does =64

Answer 2

x=+4, x= -4

Explanation:

the solutions to the quadratic equation
`4x^2= 64`

To solve the quadratic equation , solve the equation for x

`4x^2= 64`

Divide both sides by 4

`x^2= 16`

To eliminate square from x , take square root on both sides

`√(x^2) =√(16)`

When we take square root we put +-

`x=+-4`

x=+4, x= -4
