Oct 08, 2020 · A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2. There are three main ways to solve quadratic equations: 1) to factor the quadratic equation if you can do so, 2) to use the quadratic formula, or 3) to complete the square. Hence we have x2 − 3x + 1 = x2 − 3x + − + 1 = x − 2 − . Solving quadratic equations by completing the square. We can now apply the method of completing the square to solve quadratic equations. To complete the square for an equation, we will add in a factor on each side to produce a square. Quadratics - Complete the Square. Objective: Solve quadratic equations by completing the square. When solving quadratic equations in the past we have used factoring to solve for our variable. This is exactly what is done in the next example. Example 1. x2+5x +6=0 Factor (x +3)(x +2)=0 Seteachfactorequaltozero x +3=0 or x +2=0 Solveeachequation − 3 − 3 − 2 − 2 x = − 3 or x = − 2 OurSolutions However, the problem with factoring is all equations cannot be factored.

In other words, when solving a quadratic equation by the square root property, we want both the positive and negative square roots. Common Mistakes to Avoid: † Do NOT forget to include the negative square root in the answer. † Before you apply the square root property make sure the squared term is isolated. † p a+b 6= p a+ p b. PROBLEMS ... A quadratic equation, or second degree equation, is an algebraic equation of the form: ax2 + bx + c = 0,. where x is a variable and a, b and c represent known numbers such that a ≠ 0 (if a = 0 then the equation is linear). Solve the following quadratic equation by completing the square method. 9x 2 - 12x + 4 = 0. Solution : Step 1 : In the given quadratic equation 9x 2 - 12x + 4 = 0, divide the complete equation by 9 (coefficient of x 2). x 2 - (12/9)x + (4/9) = 0. x 2 - (4/3)x + (4/9) = 0. Step 2 : Subtract 4/9 from each side. x 2 - (4/3)x = - 4/9. Step 3 :
