Answer 1

x^2 - 8x + 16 = 2x^2 - x - 8x + 4

x^2 - 2x^2 -8x + x + 8x = - 12

-X^2 + x = -12 / * -1

x^2 - x = 12

x^2 -x -12 = 0

delta = 1 - 4 razy (-12) = 49

x(1na dole) = -3
x(2na dole) = 4

Answer 2

X^2 - 8x + 16 = 2x^2 - x - 8x + 4

x^2 - 2x^2 -8x + x + 8x = - 12

-X^2 + x = -12 / * -1
x^2 - x = 12
x (x -1) = 12
