What are the possible values for x in the equation [tex]4x^2 = 64[/tex]?

1) [tex]x = 0[/tex]
2) [tex]x = 4[/tex]
3) [tex]x = 4, -4[/tex]
4) [tex]x = 0, 4, -4[/tex]

4 x 2 = 64 4 x 2 − 64 = 0 / : 4 x 2 − 16 = 0 x 2 − 4 2 = 0 ( x − 4 ) ( x + 4 ) = 0 x − 4 = 0 or x + 4 = 0 x = 4 or x = − 4 A n s w er : 3 ) x = 4 , − 4
