x=3
f (3)=4.3^2-8.3+3
f (3)=36-24+3=15
f (3)=4.3^2-8.3-3=36-24-3=5
If you use the distributive property, you will multiply 4 by 2x to get 8x and 4 by -4 to get -16.
8x-16=8x+k
If you want infinitely many solutions the equations on both sides of the equal sign need to be the same. So, k would need to be -16.
