HURRYYYY

Solve 2x^2 + 8 = 0 by graphing the related function.

There are two solutions: 2 and -2

There is one solution: 2

There are no real number solutions

There are two solutions: (idk how to type this answer so I took a picture of it)

Answer 1

no real number solutions

Explanation:

made a 100% on my quiz

Answer 2

There are no real number solutions.

Explanation:

`2x^(2) +8=0\\2x^(2) =-8\\x^(2) =-4\\x=√(-4)`

Real numbers are a whole range of numbers including: Natural Numbers(1;2;3...), Whole Numbers(0;1;2...), Integers(...;-2;-1;0;1;2;...), Rational Numbers(-0.6; -0.2; 0 ;1.5 etc.) and Irrational Numbers(
`√(2)`;
`√(3)`;π; etc.). All these number comprise Real Numbers.

Imaginary Numbers are the square roots of negative Integers, which is the case for this question.
