Answer 1

What he said below was that it was your second choice

(hope this helps or at least thats what i got from it)

Answer 2

y = 3x² - 4x + 11
0 = 3x² - 4x + 11
x = -(-4) ± √((-4)² - 4(13)(11))
2(3)
x = 4 ± √(16 - 4(143))
6
x = 4 ± √(16 - 572)
6
x = 4 ± √(556)
6
x = 4 ± 2√(139)
6
x = 2 ± √(139)
