Question

Determine the solutions to the quadratic equation -4x2 - 32x - 64 = 0.

Answer 1

140

Answer 2

a= - 4
b = -32
c = -64

1st root : \[32 + \sqrt{1024+1024}/2(-4)\]
\[32 + \sqrt{2(1024)}/-8\]
\[32 + 32\sqrt{2}/-8\]
\[32(1+\sqrt{2}/-8\]
\[-4{1+\sqrt{2}}\]

2nd root :

\[32 - \sqrt{1024+1024}/2(-4)\]
\[32 -\sqrt{2(1024)}/-8\]
\[32-32\sqrt{2}/-8\]
\[-4(1-\sqrt{2})\]
