Question

x^2+5x+1+0

Answer 1

factor or simplify?

Answer 2

x^2+5x+1is the answer.

Answer 3

you have to use the quadratic formula to answer it

Answer 4

the answer choices are either -5\[-5-+\sqrt{21} \over 2 \] or 29 in the spot of 21 as well as is the 5 a positive or negitive

Answer 5

x = [-b ± √((b^2) - 4ac)]/2a
a = 1; b = 5; c = 1

x = [-5 ± √(25 - 4(1)(1))]/2
x = [-5 ± √(25 - 4)]/2
x = [-5 ± √(21)]/2

For the positive sign...
x = [-5 + √(21)]/2 ≈ -0.208712

For the negative sign...
x = [-5 - √(21)]/2 ≈ -4.79129

So your answers are exactly x = [-5 ± √(21)]/2, or more approximately x ≈ -0.208712 and x ≈ -4.79129.

Answer 6

This would make (B) the correct answer.
