Learn how to solve problems step by step online. Simplify the product of conjugate binomials (x^2-7x+-3)(x^2+7x+3). 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.. Simplify \left(x^2\right)^2 using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 2 and n equals 2. Expand the expression \left(7x+3\right)^2 using the square of a binomial. Take the square of the first term: 7x.
