a = 2 ± 2 $\sqrt{2}$

Step-by-step explanation:

a = 1

b = -4

c = -4

x = (-b ± $\sqrt{b^2 - 4ac}$ ) / 2a

x = (-(-4) ± $\sqrt{(-4)^2-4(1)(-4)}$ ) / 2(1)

x = (4 ± $\sqrt{16 +16}$ ) / 2

x = (4 ± 4 $\sqrt{2}$ ) / 2

x = 2 ± 2 $\sqrt{2}$

Your variable being solved is a so a = 2 ± 2 $\sqrt{2}$

C= 2/3

Step-by-step explanation:

Combine like terms... 5-3= 2

Subtract 4 from both sides which gives you 3c=6c-2

Subtract 6 from both sides... which equals -3c= -2

Divide both sides by 3... equals 2/3

I hope this helps!!!

Have a blessed day!!!
