$\left(45m^4-2\right)\left(9\cdot 5m^4+2\right)$
Learn how to solve special products problems step by step online. Solve the product (9*5m^4-2)(9*5m^4+2). Multiply 9 times 5. Multiply 9 times 5. 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.
