$e=3\left(x-1\right)^2+\left(3x+1\right)^2+3x^2$
Learn how to solve problems step by step online. Solve the quadratic equation e=3(x-1)^2+((3x+1)^2)/13x^2. Any expression divided by one (1) is equal to that same expression. Move everything to the left hand side of the equation. Expand \left(x-1\right)^2. Multiply the single term -3 by each term of the polynomial \left(x^2-2x+1\right).
