x2+bx is not a perfect square, how do you get it to become one then? Chapter 5: in this chapter i will teach you how to complete the square. You may be thinking how can you Complete the Square? well you add a term to create a trinomial that will make it into a perfect square. Using the algebra tiles: a quadratic equation that is used in the tiles has x2 alone it will represent . the term next to x (the coefficient) will be split in half and correctly put to the left and under the bottom of the x2 tile then comes the one...you can multiply the amount of the number you got after dividing the x tiles in half.Then add that number to the binomial to create the trinomial then find the factors which will be th x+__(<- the half of b) and the x-__(<- the half of b) then do the square root of both sides of the equation. You can also find your perfect square by completing the tile algebraically: First you identify your equation. Then, find the half of b (make sure the x2 is isolated first) after you find the half of b, square the amoun you found after you got the half. add the amount then find the square toot of both sides of the equation, finally write and solve the two equations.
