What happens if there is insufficient memory to allocate

If 27 (x+y)³ − 8(x−y)³ = (x + 5y) (Ax² + By² + Cxy), then what is the value of (A+B-C)?

If a + (1/a) = 2, then find the value of (a⁵ + a³ + 6)/(7a – 5).

When 732 is divided by a positive integer x, the remainder is 12. How many values of x are there?

If a + b + c = 6, a² + b² + c² = 14 and ab + bc+ ca = 11, then what is the value of a³ + b³ +c³ –3abc?

If sin 28° = 15/17 , then tan 62° = ?

if a² + b² + c² = 2(4a -5b -6c)-77 , then a-b-c = ?

If (a - b - c) = 6, and (ab - bc + ca) = 117, then find the value of (a² + b² + c²)

if a² + b² + c² = 2(3a -5b -6c)-70 , then a-b-c = ?
