The complete factored form of the quadratic expression is (x-8y)(x-8y)
<h3>Factorizing quadratic expression</h3>
Quadratic expressions are expressions that has a leading degree of 2
Given the expression
x^2 – 16xy + 64y^2
Factorize
x^2 - 8xy - 8xy + 64y^2
Group
(x^2 - 8xy) - (8xy + 64y^2)
x(x-8y) - 8y(x - 8y)
Since (x-8y) is common, hence;
x^2 - 8xy - 8xy + 64y^2 = (x-8y)(x-8y)
The complete factored form of the quadratic expression is (x-8y)(x-8y)
