$7\left(x-4\right)^2-3\left(x+5\right)^2=4\left(x^2-1\right)+2$
Learn how to solve problems step by step online. Solve the quadratic equation 7(x-4)^2-3(x+5)^2=4(x+1)(x-1)+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.. Multiply the single term 4 by each term of the polynomial \left(x^2-1\right). Move everything to the left hand side of the equation. Expand \left(x-4\right)^2.
