Full solution

Q. Solve for PP: (P−4)2=16(P-4)^2=16
  1. Calculate square root: Calculate the square root of 1616 to find the possible values of (P−4)(P-4).16=4\sqrt{16} = 4 or −4-4
  2. Set up equations: Set up two equations based on the square root results.\newline(P−4)=4(P-4) = 4 and (P−4)=−4(P-4) = -4
  3. Solve first equation: Solve the first equation (P−4)=4(P-4) = 4.\newlineP−4=4P - 4 = 4\newlineP=4+4P = 4 + 4\newlineP=8P = 8
  4. Solve second equation: Solve the second equation (P−4)=−4(P-4) = -4.P−4=−4P - 4 = -4P=−4+4P = -4 + 4P=0P = 0
