If x+1 is a factor if the polynomial 2x²+kx, then k =

Let, f (x) = 2x² + kx

Since, x + 1 is divided by f (x) so,

f (-1)=0

2 (-1) + k (-1) = 0

k = 2

If (3x-1)⁷ =a₇x⁷+a₆x⁶+a₅x⁵+….a₁x+a₀, then a₇+a₆+a₅+….+a₁+a₀=

If x⁵¹+51 is divide by x+1, the remainder is

If x + a is a factor of x⁴-a²x²+3x-6a, then a =

The value of k for which x-1 is a factor of 4x³+3x²-4x+k, is
