Question

root of polynomial equation of 15x-9​

Answer 1

$\sf{ \longmapsto what \: is \: the \: root \: of \: a \: polynmial}$

The roots of a polynomial are those values of the variable that cause the polynomial to evaluate to zero.

$\sf{ \longmapsto root \: of \: polynomial \: equation \: of \: 15x-9}$

$\sf{ \fbox{ let \: x = \frac{3}{5} }}$

$\sf{ \hookrightarrow ({15} \times \frac{3} {5} )- 9 }$

$\sf{ \hookrightarrow(3 \times 3) - 9}$

$\sf{ \hookrightarrow9- 9}$

$\sf \purple{ \hookrightarrow0 \: \: \: \green { \checkmark}}$

$\sf \pink{ \fcolorbox{blue}{green}{ hence, \: x = \frac{3}{5} }}$
