Slove x2 4x 3 0Solutionx2 4x 3 0 Solve by factorisationBr

Slove x^2 - 4x + 3 = 0

x^2 -4x +3 =0

Solve by factorisation:Break middle coefficients in to terms product of which is product of coeffcient

of x^2 and constant term

So, -4 =-3 -1 and -3x-1 =3

So, x^2 - 3x -x +3 =0

x(x-3) -1(x-3)=0

(x-1)(x-3) =0

So, x-1 =0 ; x=1

and x-3 =0 ; x=3
