Answer

y=(x1)21y = (x-1)^{2} - 1

Step 1: Start with the given quadratic expression.

y=x22xy = x^2 - 2x

Step 2: Factor out the leading coefficient a=1a = 1 from the x2x^2 and xx terms (not necessary here but general form).

y=1(x22x)y = 1 \cdot (x^2 - 2x)

Step 3: Complete the square inside the parentheses. Coefficient of xx is 2-2, half is 1-1, square is 11.

Add and subtract 11 inside:

y=1(x22x+11)y = 1 \cdot (x^2 - 2x + 1 - 1)

y=1((x1)21)y = 1 \cdot ((x - 1)^2 - 1)

Step 4: Distribute the leading coefficient.

y=1(x1)211y = 1 \cdot (x - 1)^2 - 1 \cdot 1

y=(x1)21y = (x - 1)^2 - 1

This is the vertex form a(xh)2+ka(x - h)^2 + k where a=1a = 1, h=1h = 1, k=1k = -1.

y = (x-1)^{2 - 1}

Step 1: Start with the given quadratic expression. y = x^2 - 2x Step 2: Factor out the leading coefficient a = 1 from the x^2 and x terms (not necessary here but general form). y = 1 · (x^2 - 2x) Step 3: Complete the square inside the parentheses. Coefficient of x is -2, half is -1, square is 1. Add and subtract 1 inside: y = 1 · (x^2 - 2x + 1 - 1) y = 1 · ((x - 1)^2 - 1) Step 4: Distribute the leading coefficient. y = 1 · (x - 1)^2 - 1 · 1 y = (x - 1)^2 - 1 This is the vertex form a(x - h)^2 + k where a = 1 , h = 1 , k = -1 . y = (x-1)^2 - 1
