Easy Medal

Answer 1

Solve.

\[(z + 7)^2 = 3\]


A. \[\left\{ 7± √3\right\}\]


B. \[\left\{ -7 + √3, 7 - √3 \right\}\]


C. \[\left\{√3 ± -7 \right\}\]


D. \[\left\{7 ± √3 \right\}\]

Answer 2

(z+7)2=3

Two solutions were found :
1. z =(-14-√12)/2=-7-√ 3 = -8.732
2. z =(-14+√12)/2=-7+√ 3 = -5.268
