How will you describe the roots of the quadratic equation x² + 3 = 5 when solved using quadratic formula? help pleasee

A. Equal

B. Irrational

C. Rational

D. Non - real

The answer is B. Sqrt= Radical symbol
1. Subtract 5 from both sides. x^2+3-5=5-5
2. New equation. x^2-2=0
3. To make it easier I am going to add 2 to the other side and take the square root of 2. x^2-2+2=0+2, x^2=2, sqrt(x^2)= sqrt(2).
4. You will get plus or minus radical 2 because when you take the square root you will always have a positive root and a negative root of any quadratic equation. x= plus and minus sqrt(2).
5. So the answer is that it’s irrational because plus and minus radical 2 is not an integer, and secondly it isn’t a perfect root which means that plus and minus radical 2 is an irrational set roots for this quadratic equation.

Do the math. she originally had 50 dollars on her gift card and she had 12 dollars left on her gift card after she finished her shopping spree. if you subtract 50 minus 12 you get thirty eight dollars as your answer. so therefore, ciara spent 38 dollars total o
