if using the method of completing the square to solve the quadratic equation x^2+17x+3=0x 2 +17x+3=0, which number would have to be added to "complete the square"?​

Respuesta :

Answer:

Step-by-step explanation:

answer:289/4

x² + 17x + 12 = 0

x² + 17x = -12

Take half of the second coefficient, square it, then add the result to both sides.

(17/2)² = 289/4

x² + 17x + 289/4 = -12 + 289/4

(x + 17/2)² = 241/4
