Answer:
-3 and 2
Step-by-step explanation:
put : x = - 3 in this equation : x - 6 = -x².
- 3 - 6 = - (- 3)²
-9 = -9 .....true
now put x = 2
2 - 6 = - (2)²
- 4 = - 4......true
Answer:
which of the following is the standard from of quadratic equation
Answer:
answers us a because that's the less sign and 1 is less than 2
To solve this, we would need to figure out the values of 
for which an absolute value is negative. From basics, you should know that an absolute value is always greater than or equal to 0.
If we rearrange this equation a little bit, we get,
So 
<em>cannot </em>be negative. So,
For this to <em>have </em>a solution, k needs to be greater than or equal to 
.
For <em>no solution</em>, k is less than -5. So, values of k which will make the equation to <em>not </em>have any solution is 
.
