Question

2 multiple choice algebra 2 questions! please help.
Solve 5x2 = –30x – 65
x = –3 ± 2i

x = –3 ± 4i

x = –6 ± 2i

x = –6 ± 4i

Solve x2 + 2x + 9 = 0

ANSWER CHOICES FOR SECOND ONE ATTACHED :)

Answer 1

5x2 = –30x – 65

\[\large{5x^2 = –30x – 65}\]
\[\large{5x^2+30x+65=0}\]

Answer 2

a = 5 and b = 30 and c = 65 : put these values here:
\[\large{\frac{-b\pm \sqrt{b^2-4ac}}{2a}}\]

Answer 3

can u solve that? :
\[\large{\frac{-30\pm \sqrt{30^2-4(65)(5)}}{2(5)}}\]

Answer 4

wowwee
my suggestion would be to divide by 5 first
