Plz EXPLAIN Q.11. The sum of all the real roots of the equation x - 2 2 + x - 2 - 2 = 0 is? Share with your friends Share 0 Amit Shukla answered this Dear Student, We have,x-22+x-2-2=0Let,x-22=ytherefore,y2+y-2=0y2+2y-y-2=0yy+2-1y+2=0y-1y+2=0y-1=0⇒ y=1⇒x-2=1⇒x-2=±1x-2=1⇒x=3 and x-2=-1⇒x=1and,y+2=0⇒y=-2but, x-2≠-2So, all the real roots are 1 and 3And the sum is 1+3= 4 Regards. 1 View Full Answer Ketki Kelkar answered this Let x to be greater than equal to 2. So x = 3 is only possible. Let x to be less than 2. x2– 5x + 4 = 0 x = 1, 4 x = 1 is only possible. So, there are two roots 1 & 3. Sum of roots is 4. Hope it will help :) 1
