1.

find the LCM of the followingexpressions - 2228 and 22-5x46

Answer»

2x^2-8=( x+4)( 2x-2); x^2-5x+6; x^2-3x+2x+6; x( x-3)+2( x-3); ( x+2)( x-3); x=-2, 3

1st term 2x^2-8=2(x^2-4)= 2(x-2)(x+2)2nd term= x^2-5x+6=x^2-3x-2x+6=x(x-3)-2(x-3)(x-3)(x-2)LCM= 2(x-2)(x+2)(x-3)= 2(x^2-4)(x-3)

X=-2, 3 is correct answer
