Question

Which equation has the same solution as x2 - 6x - 14 = 0?

Answer 1

B

Explanation:

Given

x² - 6x - 14 = 0 ( add 14 to both sides )

x² - 6x = 14

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + 9 = 14 + 9

(x - 3)² = 23 → B
