Question

3x² – 9 x + 5 = 0 x equal to​

Answer 1

Answer:

$\huge \sf \underline{given \ \: : }$

$\sf {3x}^{2} - 9x + 5 = 0$

$\sf \huge \underline{to \: find \ \: : }$

$\sf \: the \: value \: of \: x$

$\huge \sf \underline{solution \ \: : }$

$\sf {3x}^{2} + 9x + 3 = 0$

$\sf \to{3x}^{2} + 9x = 0 - 3$

$\sf \to {3x}^{2} + 9x = - 3$

$\sf \to3x(x + 9) = - 3$

$\sf \to \: x(x + 9) = \frac{ - 3}{3}$

$\sf \to \: x(x + 9) = - 1$

$\purple{\boxed{ \to x = \frac{ - 1}{x + 9} }}$
