Question

See attachment.

Answer 1

sqrt(49 * 4 *-19*13)
the equation has 2 real solutions

Answer 2

ax^2+bx+c=0
Discriminant D=b^2-4ac
13x^2+7x-19
D=49-4*13*(-19)
D=1037
D=1037
so equation has two real solutions

Answer 3

( i couldn't find my calculator)

Answer 4

also i should not have wrote sqrt!!!

Answer 5

\[x = 1/26 (\sqrt(517)-7)\]

Answer 6

\[b^2-4ac=7^2-4(13)(-19)>0\]
The solution will be two real numbers.

Answer 7

\[1/26 (-7+\sqrt(517))\] two real solutions

Answer 8

Brain has officially left the building.

\[\Large {7^2} - 4(13 \cdot - 19) = 49 + 988 = 1037\]

Answer 9

ok so it'll be choice B?
Then what to i put in the box.

Answer 10

1037

Answer 11
