Answer:
<u><em>x = ±1</em></u>
Step-by-step explanation:
x² + 0x -1 = 0
x²- 1 = 0
x² = 1
x = ±1
--------------
check
1² + 0x - 1 = 0
1 - 1 = 0
-1/2=3/2k+3/2
Rewrite the equation to have k on left side
3/2k+3/2=-1/2
Simplify 3/2k
3k/2+3/2=12
Move all terms not containing k to right side
3k/2=1/2-3/2
3k/2=-2
Multiply both sifmdes by 2
2(3k/2)=-2(2)
3k=-4
Divide both sides by 3 to get k alone
3k/3=-4/3
K= -4/3
