Question 1063211
if five times the square of a positive number is added to the product of 38 and a number, the result is 63. Find the number

{{{5x^2 + 38x = 63 }}}
{{{ 5x^2 +38x - 63 = 0 }}}
{{{ (5x -  7 ) (x + 9) = 0 }}} 
{{{  highlight (x = 7/5) }}}     ({{{x=-9 }}} is discarded due to {{{-9 <= 0 }}})

Check:
 {{{ 5*(7/5)^2 + 38(7/5) = 9.8 + 53.2 = 63 }}}
