sove by zero factoring property

64x²+48x+9=0

this is of the equation form

ax^2 +bx +c =0

so the roots of this equation are = - b + sqrt( b^2 -4ac) / 2a , b - sqrt( b^2 -4ac) / 2a

so plug a =64 b =48 c=9

roots are

= -48 + sqrt(48^2 - 4*64*9) / 2*64 , -48 - sqrt(48^2 - 4*64*9) / 2*64 ,

= -48 +sqrt(2304 - 2304) / 128 ,-48 - sqrt(2304 - 2304) / 128

= -48 /128 , -48/128

so the roos are same that is -6/16
