given
x²+kx-35 = (x-5)(x+7)
= x²+2x-35
on comparing we get k = 2
x²+kx-35 = (x-5)(x+7)
= x²+2x-35
on comparing we get k = 2

Answer:
The value of the k is 2 .
Step-by-step explanation:
As the equation given in the question be
x² + kx - 35 =(x-5)(x+7)
Simplify the R.H.S terms in the above equation
x² + kx - 35 = x² +7x -5x -35
x² + kx - 35 = x² +2x -35
kx = x² - x² + 35 -35 +2x
kx = 2x
Thus k = 2
Therefore the value of the k is 2 .
