Answer:
0 = -3x -5 +x²
Explanation:
In this context, "a" refers to the coefficient of x². Here, you're looking for the equation with a term of x², not -x² or -5x². There is only one answer choice that matches this requirement. It is shown above.
__
"b" refers to the coefficient of x, so the equation needs to have a term of -3x.
"c" refers to the constant, so the equation needs to have a constant of -5.
Taken together, you're looking for an equation equivalent to x² -3x -5 = 0.
