The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: $(a+b)(a-b)=a^2-b^2$.

$n\left(n^2-4\right)=n^3-4n$

Learn how to solve equations problems step by step online. Solve the equation n(n-2)(n+2)=n^3-4n. The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: (a+b)(a-b)=a^2-b^2.. Factor the polynomial n^3-4n by it's greatest common factor (GCF): n. Cancel n from both sides of the equation. Group the terms of the equation by moving the terms that have the variable n to the left side, and those that do not have it to the right side.
