Answer:
x=+4, x= -4
Step-by-step explanation:
the solutions to the quadratic equation [tex]4x^2= 64[/tex]
To solve the quadratic equation , solve the equation for x
[tex]4x^2= 64[/tex]
Divide both sides by 4
[tex]x^2= 16[/tex]
To eliminate square from x , take square root on both sides
[tex]\sqrt{x^2} =\sqrt{16}[/tex]
When we take square root we put +-
[tex]x=+-4[/tex]
x=+4, x= -4
