Question

Verify whether values are roots of equation or not-
(ii) x² - 4x + 4 = 0;
x=2, x=-3​

Answer 1

Answer:

x=2 is a root of equation but x= -3 is not a root

Step-by-step explanation:

x^2-4x+4=0

x^2-2x-2x+4=0

x(x-2)-2(x-2)=0

(x-2)(x-2)=0

x=2,2

Answer 2

Answer:

Step-by-step explanation:

x^2- 4x+ 4= 0

putting, x=

=2×2- 4×2+4=0

=4-8+4=0

=4-4=0

0

so,x=2 is a root of this equation.

&

putting x=-3

-3^2-4×3+4=0

=9+12+4=0

= 25=0

=25

25 is not equal to zero. so, x=-3 is not a root of thisequation.
