Question

Solve 2x2 + 16x + 34 = 0.
A. −4 ą 2i
B. −8 ą 2i
C. −8 ą i
D. − 4 ą i

Answer 1

The answer to this question is determined through the used of the equation,

( -b +/- sqrt (b² - 4ac)) / 2a

where a, b, and c are the numerical coefficients of the terms in the quadratic equation in order. Substituting the known values,

x = (-16 +/ sqrt(16² - 4(34)(2))/ 2(2)

Simplifying,
x = (-16 +/- sqrt (-4)) / 4

The answer would be,
x = -4 +/- i

The answer is letter D.
