Perfect Square Trinomial: An expression that is obtained from the square of a binomial is termed a perfect square trinomial. For example, if we square the expression (y+3), we use the identity, (a+b)2= a2 +2ab+b2, and we get, (y+3)2 = y2 +6y+9. Here, y2 +6y+9 is a ...
Afterward, simplify the perfect square trinomial to successfully transform the function into the vertex form of that quadratic function.What does Completing the Square Mean? One of the most commonly used functions in mathematics is the quadratic function. When working with quadratic functions, three ...
The criteria include having perfect squares for the first and third terms, and the middle term, when divided by 2, must equal the perfect squares multiplied together. Then and only then is the trinomial a perfect square binomial. Read Perfect Square Binomial | Definition, Formula & Examples ...
Completing the squareIf we try to solve this quadratic equation by factoring,x2 + 6x + 2 = 0 we cannot. Therefore, we will employ a method called completing the square. We will make the quadratic take the form of a perfect square trinomial: a2 + 2ab + b2 = (a + b)2 .This...
Example 1:Using completing the square formula, find the number that should be added to x2- 7x in order to make it a perfect square trinomial. Solution: The given expression is x2- 7x. Method 1: Comparing the given expression with ax2+ bx + c, a = 1; b = -7 ...
