Completing the square

x^{2}+3×=0

Answers

Answer 1
Answer: { x }^( 2 )+3x=0\n \n { \left( x+\frac { 3 }{ 2 } \right) }^( 2 )-{ \left( \frac { 3 }{ 2 } \right) }^( 2 )=0\n \n { \left( x+\frac { 3 }{ 2 } \right) }^( 2 )-\frac { 9 }{ 4 } =0

\n \n { \left( x+\frac { 3 }{ 2 } \right) }^( 2 )=\frac { 9 }{ 4 } \n \n x+\frac { 3 }{ 2 } =\pm \frac { \sqrt { 9 } }{ \sqrt { 4 } } \n \n x+\frac { 3 }{ 2 } =\pm \frac { 3 }{ 2 } \n \n x=-\frac { 3 }{ 2 } \pm \frac { 3 }{ 2 } \n \n \therefore \quad x=0,\quad and\quad x=-3.
