by quadratic equation: 2,0 -b+-(plus and minus) the square root of b^2-4ac over 2a = -(-8)+-(plus and minus) the square root of 64-4(4)(0)over 2(4) =8+-(plus and minus) the square root of 64 over 8 = 8+8 over 8 or 8-8 over 8 =2 or 0
by equating... it will become 4x(x-2)=0 then.. 4x=0 , divide both side by 4 to get the value of x..the answer would be 0. the other one is x-2=0 transpose 2 to the right side to get the value of x.. and it would be 2.
