Question

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

Answer 1

Answer:

Step-by-step explanation:

X²-8x+18 = 0

(x) ²-2×x×4 + (4)² +18 - 16 = 0

(x-9)² = -18+16

(x-9)² = -2

X-9 = /-2

This is not possible. So it has no solution

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
