Question

Sole by the quadratic formula: 4x^2-8x+1=0
Please explain

Answer 1

- b + - sqrt(b^2 - 4ac)/(2a) <-----quadratic formula

Answer 2

b = -8, a = 4, c =1 ---- plug in values and solve

Answer 3

x=\[[-(-8)+/-\sqrt{(-8^2)-4(4)(1)}]/2(4)\]
x=\[{8+/-\sqrt{64-16}}/8\]
x=\[8+/-\sqrt{48}/8\]
x=\[[8+/-(4\sqrt{3})]/8\]
x=[2+\[\sqrt{3}/2\]], 2-\[\sqrt{3}/2\]
x=1.866,0.134
