Answer:
The correct answer choice is D
Step-by-step explanation:
Given the quadratic equation:
y=x^2-x-5
We are required to find the zeros using the quadratic formula.
The quadratic formula is given as:
x= -b+ square root b^2-4ac/2a
Comparing the given equation with the standard form of a quadratic equation: y=ax²+bx+c
a=1, b=-1,c=5
Substitute these values into the formula.
x=1(-)
