Factor x2−4x^2-4.
Factor 4x2 + 12x + 9 by recognizing it as a perfect square trinomial.
Given the polynomial 125z3−8125z^3-8, factor completely.
Why can the sum x2+y2x^2+y^2 not be factored into binomials with real coefficients using the difference-of-squares rule?
A student attempts to factor x² + 6x + 10 by applying the perfect square trinomial formula and obtains (x + 3)². Evaluate whether this is correct and justify your conclusion.
