Question

Use the quadratic formular to solve the equation
1/4 x^2 - 1/2 x=1

Answer 1

(1/4)x^2-(1/2)x-1=0

substitute a=1/4
b=-1/2
c=-1
in formula:
\[\LARGE x_{1/2}=\frac{ -b \pm\sqrt{b^2-4ac }}{2a}\]

Answer 2

1/2(+)(-)under root 5/4 / (1/2)

Answer 3

Is this correct?
1-sqrt5 , 1+sqrt5

Answer 4

Answer 5

1/4 x^2 -1/2 x =1
x^2 -2x -4=0

x_1,2=(2+/- sqrt(4+16))/2 =(2+/- 2sqrt5)/2 = 1+/- sqrt5
