root question

b???//
not sure
any one please method batana
any short cut for t

Since it is give that:
x^2/by+cz = 1 ==> x^2 = by+cz ; add ax on both sides we get
x(a+x) = ax+by+cz=>a/a+x = ax/ax+by+cz---(1)
Similarly, b/b+y = by/ax+by+cz and c/c+z = cz/ax+by+cz;
Add all three, we get a/a+x + b/b+y + c/c+z = 1

.75^3/.25 = 3 * .75^2
=> 4*.75^2 +.75+1
=> 9/4 + 3/4+1= 4


@sumitrewri said:
0

cube on both side

& derive the equation by taking x^6 common

B) 2
.75^3/.25 = 3 * .75^2
=> 4*.75^2 +.75+1
=> 9/4 + 3/4+1= 4
squareroot b le lo yaar
