Question

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

Answer 1

Answer:

x=+4, x= -4

Step-by-step 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

$\sqrt{x^2} =\sqrt{16}$

When we take square root we put +-

$x=+-4$

x=+4, x= -4

Answer 2

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