Question

If (X+2) is the factor of 2x^2+3x+2k +3 then find the value of k..... Plzz answer fast with full explaination .......

Answer 1

Answer:

k = 2.5

Step-by-step explanation:

x+2 is a factor.

So when we substitute x= -2, we should get the whole equation equivalent to zero.

2x^2+3X+2K+3=0

2(-2)^2+3(-2)+2K+3=0

2(4)-6+2K+3=0

8-6+2K+3=0

2k+5=0

2K= -5

K = -5/2

k = -2.5
