Completing the square is an algebraic technique that converts a quadratic expression into perfect square form. It's used to solve quadratics and rewrite parabola equations in vertex form.

ସୂତ୍ର

ax² + bx + c = a(x + b/2a)² + (c - b²/4a)

  1. 1Identify coefficients a, b, c
  2. 2Move constant to the right side
  3. 3Add (b/2a)² to both sides to complete the square

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
x² + 6x + 5 = 0
ଫଳ
(x + 3)² = 4 → x = -1 or x = -5
Completing the square yields vertex form

  • Forgetting the a coefficient when factoring out
  • Adding wrong value to complete the square
