Let f(x)={x+1,x>0 and 2-x,x<=0g(x)={x+3,x<1 and x^(2)-2x-2,1<=x<2 and x-5

Given A={x:x is a root of x^(2) -1=0} B={x:x is a root of x^(2) -2x+1=0} then

Given A={x|x is a root of x^(2)-1=0},B={x|x is a root of x^(2)-2x+1=0}. Then

If alpha,beta are the roots of the equation x^(2)+x+1=0 , then the equation whose roots are alpha^(22)andbeta^(19) , is a) x^(2)-x+1=0 b) x^(2)+x+1=0 c) x^(2)+x-1=0 d) x^(2)-x-1=0

Let x=1+(1)/(1+(1)/(1+(1)/(1+(1)/(1+(1)/(1+alpha))))). Which of the following is correct? x^(2)+x+1=0 (b) x^(2)-x+1=0( c) x^(2)+x-1=0 (d) x^(2)-x-1=0

If x^(2) - 2x + 1 = 0 "then" x + 1/x =

Determine the nature of the roots of the following quadratic equations: 2x^2+x-1=0 x^2-4x+4=0 x^2+x+1=0 4x^2-4x+1=0 2x^2+5x+5=0

Given A = {x | x is a root of x^2 - 1 =0}, B = {x | x is a root of x^2 - 2x + 1 = 0} . Then

0.1^(4x^(2)-2x-2)<=0.1^(2x-3)
