Answer:

Well we know that it's a linear because it has a exponent so what we do to answer this question

Step-by-step explanation:

------

- b+ v. b2 -4ac

x= ____________

2a

x2+ 12x +20 =0

a=1

b=12

c=20

_______

X= -12+v 12 2 -4 • 1 • 20

___________________

2•1

Answer:

2; 10

Step-by-step explanation:

12/2 = 6

[tex](x+6)^{2}[/tex] = [tex]x^{2}[/tex] +12x + 36

   [tex]x^{2}[/tex] +12x + 20

-   [tex]x^{2}[/tex] +12x + 36

    0 + 0  - 16

[tex](x+6)^{2}[/tex] - 16 = 0

[tex](x+6)^{2}[/tex] = 16

x + 6 = [tex]\sqrt{16}[/tex]

x = -4 + 6 = 2

x = 4 + 6 = 10
