Question

$$\frac{ { x }^{ 2 } -5x }{ 8 } = \frac{ 3 }{ 4 }$$

Answer

x=6,-1

Solution


Factor out the common term \(x\).
\[\frac{x(x-5)}{8}=\frac{3}{4}\]
Multiply both sides by \(8\).
\[x(x-5)=6\]
Expand.
\[{x}^{2}-5x=6\]
Move all terms to one side.
\[{x}^{2}-5x-6=0\]
Factor \({x}^{2}-5x-6\).
\[(x-6)(x+1)=0\]
Solve for \(x\).
\[x=6,-1\]
