What is the solution of the equation when solved over the complex numbers? x^2+27=0

(0,27)

Step-by-step explanation:

x2 + 27 = 0

Solutions based on quadratic formula:

x1  

= −0 − √ 02 − 4×1×27   2×1 = 0 − 6 × √ 3 i   2 ≈ −5.196152i

x2  

= −0 + √ 02 − 4×1×27   2×1 = 0 + 6 × √ 3 i  2 ≈ 5.196152i

Extrema:

Min = (0, 27)

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
