Question

final the root of quadratic equation x²-5=0
​

Answer 1

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.

The answers should be x = ±√5
