Question

one correct answer type questions :
Factors of x2-3x +2 are
a) x-1
b)x-2
c)x+1
d)x+2​

Answer 1

Given x

2

−3x+2=0

x

2

−2x−1x+2=0 (Resolving the expression)

x(x−2)−1(x−2)=0 (Taking common factors)

(x−2)(x−1)=0 (Taking common factors)

∴x−2=0 or x−1=0 (Equating each factor to zero)

∴x=2 or x=1

∴2 and 1 are the roots ....

Answer 2

Answer:

(x-1)(x-2)

Step-by-step explanation:

x^2-3x+2

=x^2-x-2x+2

=x(x-1)-2(x-1)

=(x-1)(x-2)

It's done mate!
