Question

If x+1 is a factor of polynomial 2x^2+kx-3 then find the value of x

Answer 1

Step-by-step explanation:

x +1 is a factor

x+1= 0(By factor theorem)

x = -1

Put the value of x in the equation

2*(-1)(-1)+k(-1) -3 = 0

2-k=3

k=-1

Put the value of k in the equation

2x^2-x-3= 0

Now solve by middle term factorisation.

x = 3/2 or -1
