What is x2-6x plus 5 equals 0?

Answer 1

solving for the x variable given that x2-6x+5=0

factoring the polynomial gives (x-1)(x-5)=0 which leaves you with your two answers, x=1, 5

or you could have used the quadratic equation

x = [ -(-6) plus/minus sqrt( (-6)2 - 4*1*5 ) ] / (2*1)

x = [ 6 plus/minus sqrt( 36-20 ) ] / 2

x = [ 6 plus/minus 4 ] / 2

x = 3 plus/minus 2

x = 5, 1
