how would you solve this

Question

Using formula:( x= -b/2a )

 

Equation: y= x^2-2x+1

Answer 1

Stephanie,

 

There are 2 ways of solving

 

A quadratic equation is y = ax^2+bx+c

In this case

y = x^2-2x+1 , so a = 1 and b = -2

Solving for x = -b/2a = -(-2)/(2*1) = 1

 

or you can solve the equation

x^2 -2x + 1 = 0

x^2 -x -x + 1 = 0

x(x-1) -1(x-1) = 0

(x-1)(x-1) = 0

or x = 1
