Factor y^2-8y+16

Problem

y2−8*y+16

Solution

1. Identify the structure of the quadratic expression, which is in the form a*y2+b*y+c where a=1 b=−8 and c=16

2. Recognize that the expression is a perfect square trinomial because the first term is y2 the last term is 4 and the middle term is −2*(y)*(4)

3. Apply the formula for a perfect square trinomial, which states a2−2*a*b+b2=(a−b)2

4. Substitute a=y and b=4 into the binomial square form.

Final Answer

y2−8*y+16=(y−4)2
