Solve by completing the square:X^2+6x-12=0
Ira Lisetskai [31]
X² + 6x  -12 = 0
x = <u>-(6) +/- √((6)² - 4(1)(-12))</u>
                     2(1)
x = <u>-6 +/- √(36 + 48)</u>
                   2
x = <u>-6 +/- √(84)
</u>              2<u>
</u>x = <u>-6 +/- 2√(21)
</u>               2<u>
</u>x = -3 <u>+</u> √(21)
x = -3 + √(21)      x = -3 - √(21)
