Question

using completing the square method show that the equation X square - 8 x + 18=0 has no solution

Answer 1

I think the following solution will help you.

Answer 2

Step-by-step explanation:

X² - 8x + 18 = 0

X² - 8x = -18

X² - 8x + 16 = -18 + 16

( X - 4 )² = -2

Since √D < 0

Thus there are no real roots, and hence the equation has no solution.
