Question

help me write this expression in factored form: x^2-4x+1

Answer 1

it does not factor over the integers, but if you find the two zeros \(r_1\) and \(r_2\) then you can factor it as
\[(x-r_1)(x-r_2)\]

Answer 2

u can use quadratic formula
x = (-b +- sqrt(b² -4ac)) / 2a
or
x^2 - 4x +1 = 0 (I'm assuming)
x^2 -4x =-1
x^2-4x +4 = 3
(x-2)^2 = 3
x-2 = + or - square root(3)
x= 2+ or - square root (3)
