Step-by-step explanation:
[tex]x {}^{2} + 4x + 5 \\ x {}^{2} + 5x - x + 5 = 0 \\ x(x + 5) - 1(x + 5) = 0 \\ (x - 1)(x + 5) = 0 \\ x - 1 = 0 \: \: \: \: \: \: \: x + 5 = 0 \\ x = 1 \: \: \: \: \: x = - 5[/tex]
Answer:-5/6
Step-by-step explanation:
x*2+4x+5=0
add similar elements: 2x+4x=6x.
6x+5=0
Subtract 5 from both sides.
6x+5-5=0-5.
simplify.
6x=-5
divide both sides by 6
6x/6=-5/6
answer
-5/6
