Simplify the quadratic equation:
10z24z=5z+2
1z24z+5z2=0
10z2+z2=0
Factorize the quadratic equation
10z2+5z4z2=0
5z(2z+1)1(2z+1)=0
(5z1)(2z+1)
Use the principle of zero products which states that if the product of two numbers is zero then at least one of the factors is 0.
(5z1)=0or(2z+1)=0
z15 or z=12
