Question

x^2+7x+2=0

Answer 1

use same formula as satalite told u in last question of urs

Answer 2

in this one the "middle term" 7x has an odd coefficient, so it is best just to use the formula
\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]

Answer 3

be careful with the signs under the radical. it is best two write out a, b, and c at the beginning via
a = 1
b = 7
c = 2
then you will know what to substitute in the formula

Answer 4

-7+-square root of 41/2

Answer 5

looks right to me!

Answer 6
