The factors of x⁴ + x² + 25 are

The factors of x² + 4y² + 4y − 4xy − 2x − 8 are

The factors of x³ − 7x + 6 are

The expression x⁴ + 4 can be factorized as

If 3x = a + b + c, then the value of (x − a)³ + (x −b)³ + (x − c)³ − 3(x − a) (x − b) (x −c) is

If (x + y)³ − (x − y)³ − 6y(x² − y²) = ky², then k =

If x³ − 3x² + 3x − 7 = (x + 1) (ax² + bx + c), then a + b + c =
