Given that x^2 + kx - 6 =
(x-2)(x+3)
We need to find
k.
First we will need to open the brackets on the left side
and then compare the terms.
==> x^2 + kx -6 = x^2
-2x + 3x - 6
==> x^2 + kx -6 = x^2 + x
-6
Now we will add 6 to both
sides.
==> x^2 + kx = x^2 +
x
Now we will subtract
x^2
==> kx = x
Now we
will subtract x from both sides.
==> kx -x =
0
Now we will factor
x.
==> x (k-1) = 0
x
can not be zero.
Then k-1 = 0 ==> k=
1
Then the value of k is
1.
