Solve the equation using square roots. Check your solution(s). 1. x2 + 4x + 4 = 36 2. x2 − 6x + 9 = 1 3. x2 − 22x + 121 = 81 In Example 1, the expression x2 − 16x + 64 is a perfect square trinomial because it equals (x − 8)2. Sometimes you need to add a term to an expression x2 + bx to make it a perfect square trinomial.

perfect squares are called square roots.Both 5 ? 5 and (25)(25) equal 25.So, 25 has two square roots, 5 and 25.A radical sign , Ïw, is the symbol used to indicate the positive square root of a number.So, Ï25w 5 5.

Completing the Square - University Academic Success …

Completing the Square Say you are asked to solve the equation: x² + 6x + 2 = 0 We cannot use any of the techniques in factorization to solve for x. In this situation, we use the technique called completing the square. This makes the quadratic equation into a perfect square trinomial, i.e. the form a² + 2ab + b² = (a + b)².

not a perfect square. So we can also say that if a natural number cannot be expr essed as a sum of successive odd natural numbers starting with 1, then it is not a perfect square. We can use this result to find whether a number is a perfect square or not. 4. A sum of consecutive natural numbers Consider the following 32 = 9 = 4 + 5 52 = 25 = 12 ...
