e following sums :-
3x2 + x(x+2) - 3x(2x+1)
(m?n4 + mºn - mºn?) + (-mºn)​

Answer 1

Answer:

Answer

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 of x

2

−3x+2=0
