solve for x: x(5x+1)=3(5x+1) x= or x=

OpenStudy (gschibby):

\[x(5x+1) \rightarrow (x*5x)+(x*1) \rightarrow 5x ^{2}+x\]

Did you find your answer? :)

OpenStudy (gschibby):

\[5x ^{2}-14x-3=0\]

OpenStudy (gschibby):

\[x=\frac{ 14\pm \sqrt{14^{2}-4*5*(-3)} }{ 2*5 }=\frac{ 14\pm16 }{ 10 }\]

OpenStudy (gschibby):

\[x=3 \] \[x=-0.2\]
