Answer:
x^2 - 8x + 16 = 0
Step-by-step explanation:
Equation 1 :
x^2 - 8x + 16 = 0
x^2 -4x -4x +16 = 0
x (x - 4) -4 (x - 4) = 0
(x - 4)(x- 4)= 0
x= 4
x= 4
x=(4) this Equation have only one solution
Equation 2:
x(x-1)=8
x^2 - x - 8 = 0
After performing quadratic equation on the equation
Answer Comes
x =(3.37 , -2.37)
Equation 3:
x^2 = 16
take square root
sqrt(x^2) = sqrt(16)
x= (+4,-4)
