Let's solve your equation step-by-step.
4(4x−8)2+16=25
Step 1: Simplify both sides of the equation.
64x2−256x+272=25
Step 2: Subtract 25 from both sides.
64x2−256x+272−25=25−25
64x2−256x+247=0
Step 3: Factor left side of equation.
(8x−13)(8x−19)=0
Step 4: Set factors equal to 0.
8x−13=0 or 8x−19=0
x=13/8 or x=19/8
