$\left(x+7\right)^2-81=25\left(x+2\right)^2$
Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation 25(x+2)^2=(x+7)^2-81. Rearrange the equation. We need to isolate the dependent variable x, we can do that by simultaneously subtracting -81 from both sides of the equation. Expand the expression \left(x+7\right)^2 using the square of a binomial: (a+b)^2=a^2+2ab+b^2. Move everything to the left hand side of the equation.
