Question

i give medals and fans

Answer 1

\[x^2 + 2x + 9 = 0\]

Answer 2

x² + 2x - 9 = 0
x = [ - 2 ± √ (4 + 36 ) ] / 2
x = [ - 2 ± √ (40) ] / 2
x = [ - 2 ± 2√(10) ] / 2
x = - 1 ± √10

Answer 3

oops i did this wrong.

Answer 4

x = [ - b ± √ ( b ² - 4 a c ) ] / 2 a
x = [ - 2 ± √ ( 4 - 36 ) ] / 2
x = [ - 2 ± i √32 ] / 2
x = [ - 2 ± i 4 √2 ] / 2
x = - 1 ± i 2 √2
