Question

Which is not the root of the quadratic equation x²-6x+5 = 0 A. 1 b. 5 C 6 d. None of these​

Answer 1

Answer:

C) 6

Step-by-step explanation:

Given Quadratic Equation ;

x² - 6x + 5 = 0

A ) 1

(1)² - 6 (1) + 5 = 0

1 - 6 + 5 = 0

- 5 + 5 = 0

A) 1 is the root of Quadratic Equation

B) 5

x² - 6x + 5 = 0

(5)² - 6 (5) + 5 = 0

25 - 30 + 5 = 0

-5 + 5 = 0

B) 5 is the root of given Quadratic Equation

C) 6

x² - 6x + 5 = 0

(6)² - 6 (6) + 5 = 0

36 - 36 + 5 = 0

5

C) 6 is not the root of given Quadratic Equation
