Answer: 0
Simplify both sides of the equation
[tex]25z^2-15z+2=25z^2-15z+2[/tex]
Subtract 25z² from both sides
[tex]25z^2-15z+2-25z^2=25z^2-15z+2-25z^2[/tex]
[tex]-15z+2=-15z+2[/tex]
Add 15z to both sides
[tex]-15z+2+15z=-15z+2+15z[/tex]
[tex]2=2[/tex]
Subtract 2 from both sides
[tex]2-2=2-2[/tex]
Final Answer: [tex]0=0[/tex]
