Sagot :

                                   4 x²  =  64

Divide each side by  4 :     x² = 16

Take the square root
of each side:                     x = √16

                                   x = + 4
and
                                   x = - 4 .
4x^2=64 divide both sides by 4 x^2=16 x= +4, -4 hope this helps
