बहुपद `3x ^ 2 + 2x - 1 =0` को हल कीजिए ।

if A,B,C,D are the sum of the roots of the roots of 2x ^2 +x +3=0 , x^2 -x+2=0, 3x ^2 - 2x +1 =0 , x^2 -x-x+1=0 then the ascendinf order of A,B,C,D is

If |{:(x^(2) +x , 3x - 1 , -x + 3),(2x +1 , 2 + x^(2) , x^(3) - 3),(x - 3, x^(2) + 4, 3x):}| = a_(0) + a_(1) x + a_(2) x^(2) + .... + x_(7) x^(7), then the value of a_(0) is

If 9x^2+y^2=37 and xy = 2 , x, y> 0 , then the value of (27x^3+y^3) is : यदि 9x^2+y^2=37 और xy = 2 , x, y> 0 , तो (27x^3+y^3) का मान ज्ञात कीजिए ।

The non -integral roots of x^(4) - 3x^(3) - 2x^(2) + 3x + 1=0" " (1) are

If 3x^2-5x+1=0 , then the value of (x^2+ 1/(9x^2)) is : यदि 3x^2-5x+1=0 , तो (x^2+ 1/(9x^2)) का मान ज्ञात कीजिए ।
