$14400\left(0.125z^2-0.2\right)\left(0.125z^2+0.2\right)$
Learn how to solve special products problems step by step online. Solve the product 120^2(1/8z^2-1/5)(1/8z^2+1/5). Calculate the power 120^2. 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.. The power of a product is equal to the product of it's factors raised to the same power. Multiply the single term 14400 by each term of the polynomial \left(0.0156z^{4}-0.04\right).
