Which of the following could be the value of in the equation above?

1

X^2+kx+3=0 k is a negative number

I’m assuming you meant “value of x?”

If k = -4, then x = 1 and x = 3 are solutions and possible values of x…

3

Yes dude!! You’re right, it says find the value of x but from where did you get the k=-4???

@Sacados1 Assuming I interpreted the question correctly as, k is any negative number, what is a possible value of x (where x is nonnegative, according to grid-in restrictions):

I just plugged in x = 1 as a “possible” value of x --> 1^2 + 1*k + 3 = 0. Solving, k = -4. Here, we have that k is negative, and x^2 - 4x + 3 indeed has x = 1 and 3 as solutions. This is kind of a back-solving method because there are tons of possible answer choices.

FINALLY got it!!! Thank you SOO much!!!

Btw is this question multiple-choice or grid-in? If it is grid-in, you could show that any positive value of x could be a solution in the equation.

Multiple choice dude

@Sacados1 I just looked at it; there seems to be an error because there is no positive integer solution.
