Answer 1

answer=a edg 2020

Explanation:

Answer 2

Answer:
`x=\±2√(10)`

Explanation:

To find the solutions of the quadratic equation given in the problem, you can apply the proccedure shown below:

- Subtract 40 from both sides of the equation.

- Multiply both sides of the equation by -1

- Apply square root to both sides of the equation.

Therefore, by applyin the steps above, you obtain:

`40-x^2-40=0-40\\-x^2=-40\\(-1)(-x^2)=(-40)(-1)\\\\x^2=40\\\\√(x^2)=\±√(40)\\\\x=\±2√(10)`
