Solving Quadratic Equation:

X 2 + 7x + 10 = 0 Solving Quadratic Equation ( x + 5 ) ( x + 2 ) = 0 X = -5 X = -2 X 2 + 8x + 11 = 0

Solving Quadratic Equation by Completing The Square:

X 2 + 8x + 11 = 0 Solving Quadratic Equation by Completing The Square X 2 + 8x = -11 + 16 + 16 (x + 4 ) (x + 4 ) = √ (x + 4 ) 2 = 5 5 √ X + 4 = ± 5 √ X = - 4 + √ 5 x = - 4 - √ 5

Find the roots or the solution sets of each of the following quadratic equations by Completing the square.:

Find the roots or the solution sets of each of the following quadratic equations by Completing the square . x 2 + 6x + 5 = 0 X 2 - 8x + 6 = 0 X 2 – 2x – 8 = 0 X 2 + 10x + 16 = 0 X 2 – 12x + 20 = 0

Assignment::

Solve the following quadratic equation by Completing the squares. x2 - 3x +5= 0 X2 +6x -14 = 0 X2 + 8x – 2 = 0 X2 -12x = 9 X2 -12x = 7 Assignment:
