Question

Solve the equation. -1/8(x-16) 1/8(x-8)=x+5

Answer 1

x=3,29

Answer 2

How do I get to my answer?

Answer 3

\[-\frac{ 1 }{ 8(x-16) }*\frac{ 1 }{ 8(x-8) }=x+5\]

Ur question is this?

Answer 4

Yes.

Answer 5

\[\frac{ -1 }{ 64(x-16)(x-8) }=x+5\]

\[\frac{ -1 }{ 64(x^2-8x-16x+128) }=x+5\]

\[\frac{ -1 }{ 64(x^2-24x+128) }=x+5\]

\[\frac{ -1 }{ 64x^2-1536x+8192 }=x+5\]

\[-1=(x+5)(64x^2-1536x+8192)\]

\[-1=(64x^3-1536x^2+8192x+320x^2-7680x+40960)\]

\[64x^3-1216x^2+512x+40961=0\]
