Answer:

The value of the k is 2 .

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 .

Hope it helped...
