Question

Determine whether x = − 1 is a root of the equation x^2 − 3x + 2 = 0 or not.

Answer 1

no because when -1 is used in tplace of x and solved the left hand side is not equal to the right hand side

Answer 2

Step-by-step explanation:

x= -1

Putting the value of con the equation

We get

(-1)^2 -3 × (-1 ) + 2 = 0

1+3+2 = 0

6=0

Hence RHS is not =LHS

Therefore x=-1 is not= to given equation
