Step-by-step Solution
Specify the solving method
A binomial squared (difference) is equal to the square of the first term, minus the double product of the first by the second, plus the square of the second term. In other words: $(a-b)^2=a^2-2ab+b^2$

Learn how to solve definition of derivative problems step by step online. Find the derivative of 6x+1-(7x-4)^2 using the definition. A binomial squared (difference) is equal to the square of the first term, minus the double product of the first by the second, plus the square of the second term. In other words: (a-b)^2=a^2-2ab+b^2. The power of a product is equal to the product of it's factors raised to the same power. Simplify the product -(49x^2-56x+16). Simplify the product -(-56x+16).
