Question

What are the exact solutions of x2 + 5x + 2 = 0?

x = the quantity of negative 5 plus or minus the square root of 33 all over 2

x = the quantity of 5 plus or minus the square root of 33 all over 2

x = the quantity of negative 5 plus or minus the square root of 17 all over 2

x = the quantity of 5 plus or minus the square root of 17 all over 2

Answer 1

use the quadratic formula.
For
\( x^2+5x+2=0\),
a=1
b=5
c=2
where a,b and c are coefficients of the decreasing powers.
The solution to the above equation is then
\(\huge x = \frac{-b\pm\sqrt{b^2-4ac}}{2a} \)

Answer 2

I got D am I right?

Answer 3

Answer 4

It's close but not quite the right one.
If you notice that x=-b plus or minus...
and that b=+5, then D is not the right answer.
