 = ? if a2 + b2 + c2 = 2(3a -5b -6c)-70 , then a-b-c = ?
If
= -2 then find If a = (√2 - 1)1/3, then the value of (a-1/a)3 +3(a-1/a) is:
If x² + px + q = 0 has roots 4 and -3, find the values of p and q.
Calculate the value of the expression: {2 X (P3Â - Q3) - 30 X P X Q} if (P - Q) = 6 and (P2Â + Q2) = 80
- Find the value of the expression {(4096) n /4  × 8 3n + 1 }/{(512) n  × 8 n – 1 }.
If, 4x2 + y2 + 12x + 6y + 18 = 0, then find the value of (2x + y)/(y + 6x).

If [8(x + y)3 – 27(x – y)3] ÷ (5y – x) = Ax2 + Bxy + Cy2, then the value of (A2 - 2B + 3C)...
