Answer:
The answers should be x=±√5
Step-by-step explanation:
A quadratic equation is written in the form:
ax2+bx+c=0
The given equation
x2−5=0 can be rewritten as x2+0x−5=0
Where:a=1, b=0, c=−5
The quadratic formula can be used to find the roots of any quadratic equation.
x = −b±√b2−4ac/2a
So I encourage you to plug in the values from this equation and simplify.
