Answer 2

use the quadratic formula
\[x={-b\pm\sqrt{b^2-4ac}\over2a}\]

Answer 3

can you find two numbers that multiply to 3 and add to 10 at the same time?

Answer 4

-1 -3

Answer 5

-1 and -3 add to -4, but they do not add to 10

Answer 6

hmmm hint?

Answer 7

use the quadratic formula
a = 1
b = 10
c = 3

Answer 8

there are no such numbers that multiply to 3 and add to 10 at the same time

so x^2 + 10x + 3 is prime

if you want to solve x^2 + 10x + 3 = 0, you'll have to use the quadratic formula
