निम्नलिखित व्यंजको के लघुतम समापवर्तक ज्ञात कीजिये -
`x^(2)-1,(x^(2)+1)(x+1)` तथा `x^(2)+x-1`

x का मान ज्ञात करो - (2)/(3)[4x-1] -[4x-(1-3x)/(2)]=(x-7)/(2)

((x+1)/(x^(2/3)-x^(1/3)+1)-(x-1)/(x-x^(1/2)))=

(1-2x+x^(2))/(1-x^(3))times(1+x+x^(2))/(1+x)

If y=(x^(2)+x+1)/(x^(2)-x+1)," then "(x^(2)-x+1)^(2)y_(1)=

Prove that |(1,x,x^2),(x^2,1,x),(x,x^2,1)|=(1-x^2) .

(x-1) / (2x + 1) + (2x + 1) / (x-1) = (5) / (2), x! =-(1) / (2), 1

The factor of x^8 + x^4 +1 are (A) (x^4 + 1 - x^2), (x^2 +1 +x), (x^2 + 1 - x ) (B) x^4 + 1 -x^2 , (x^2 - 1 + x), (x^2 +1 + x) (C ) (x^4 - 1 + x^2, (x^2 - 1 + x), (x^2 + 1 + x) (D) (x^4 -1 + x^2), (x^2 + 1 - x), (x^2 + 1 +x)

f(x)={(1-x, x le1/2),(x,x gt 1/2):} at x=1/2
