WebExample 1: Given x 2 + 5x + 6 = 0. ( x + 3) ( x + 2) = 0 (factoring the polynomial) ( x + 3) = 0 OR ( x + 2) = 0. Thus x = −3, Or x = −2. The example above shows that it is indeed easy to solve quadratics by factoring method. However, the method only works for the most basic equations. Ideally the method will only work on quadratics with ... WebSolve Quadratic Equation by Completing The Square. 3.2 Solving x2-8x+15 = 0 by Completing The Square . Subtract 15 from both side of the equation : x2-8x = -15. Now the clever bit: Take the coefficient of x , which is 8 , divide by two, giving 4 , and finally square it giving 16. Add 16 to both sides of the equation :

WebIt takes a few steps to complete the square of a quadratic equation. First, arrange your equation to the form ax2 + bx + c = 0. If a ≠ 1, divide both sides of your equation by a. Your b and c terms may be fractions after this step. … WebNow I can solve each factor by setting each one equal to zero and solving the resulting linear equations: x + 2 = 0 or x + 3 = 0. x = −2 or x = − 3. These two values are the solution to the original quadratic equation. So my answer is: x = −3, −2.

WebWe can refer to the expression x2 – 8x + 15 as y i.e. y = x2 – 8x + 15. Now what will be the numerical value of y? Obviously the value of y also keeps changing as the value of x changes i.e. the numerical value of y depends on the value assumed by x. If x = –2, y = 35, if x = 0, y = 15 and if x = 2, y = 3.
