Question

Solve 2x2 + 26 = 0 to identify the roots.

Answer 1

The answer is B ( the second choice)

2x^2 + 26 = 0

(Divide both sides by 2)

x^2+ 13=0

(Move the 0 and change the sign)

x^2= -13

(Simplify)

x= - 13i and x= 13i

Answer 2

X= - 0/2 ± √ (0/2)^2-13

X= ± √0^2-13

X= ± √-13

X= ± √13 i



Solution:

option B
