Answer 4

0 = x2 + 10x + 5
Let's use the quadratic formula, it's the most fun.

Answer 5

\[x = \frac{ -b \sqrt{b^{2} - 4ac} }{ 2a }\]

Answer 6

0 = x2 + 10x + 5
0 = ax^2 + bx + c
a = 1
b = 10
c = 5

Answer 7

ok i got x=[ - 5 ± 2√5] / 2

Answer 8

is it right

Answer 9

\[x = \frac{ -10 \sqrt{10^{2} - 4(1)(5)} }{ 2(1) }\]

Answer 10

and what should i write for part 2

Answer 11

Part 2: Using complete sentences, explain why you chose the method you used.
I used it because I am more familiar with it than the other methods.

Answer 12

Now I'ma solve for x

Answer 13

thanks for the help

Answer 14

i think i am right on my answer

Answer 15

i gotta go bye

Answer 16

\[x = \frac{ -10 \sqrt{10^{2} - 4(1)(5)} }{ 2(1) }\]
\[x = \frac{ -10 \sqrt{100 -20} }{ 2 }\]
\[x = \frac{ -10 \sqrt{80} }{ 2 }\]
\[x = -20\sqrt{5}\]
