Problem 3X2 + 18X − 6=0 1.

By completing the square, we can give the answer exactly using surds e.g. 1) x2 + 2x − 24 = 0 2) p2 + 12p − 54 = 0 3) x2 − 8x + 15 = 0 4) r2 + 18r + 56 = 0 5) m2 − 6m − 55 = 0 6) m2 − 4m − 91 = 0 7) m2 + 16m − 32 = −7 8) r2 − 8r = −8 9) n2 = −14n − 37 10) n2 − 2n = 15 11) x2 + 15x + 15 = 2 + x 12) −3n2 + 4n − 59. Furthermore, to complete into a perfect square, we need to add to it.

The Completing The Square Formula Is Given By, Ax2 + Bx + C ⇒ A (X + M)2 + N.

Xx2 x+ 6 x____ x b. In this situation, we use the technique called completing the square. Using the formula or approach of the complete square, the quadratic equation in the variable x, ax 2 + bx + c, where a, b and c are the real values except a = 0, can be transformed or converted to a perfect square with an additional constant.

Separate The Variable Terms From The Constant Term.

The form a² + 2ab + b² = (a + b)². The quadratic formula the above technique of completing the square allows us to derive a general formula for the solutions of a quadratic called the quadratic formula. Solving a quadratic equation by completing the square.
