Final answer to the problem
Step-by-step Solution
Learn how to solve completing the square problems step by step online. Factor the expression w^4+100-45w^2. We can factor the fourth degree trinomial w^4+100-45w^2 by applying the substitution: y=w^2. Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial y^2+-45+\frac{2025}{4}. Simplify the addition \left(y- \frac{45}{2}\right)^2+100-\frac{2025}{4}.
