Question

please tell me the answer fast
It in from the quadratic equation ​

Answer 1

$= 2 {x}^{2} + 6x - 216 = 0$

steps:

${x}^{2} = 225 - {(x + 3)}^{2}$

${x}^{2} = 225 - ( {x}^{2} + {3}^{2} + 2(x)(3)$

$= {x}^{2} = 225 - {x}^{2} - 9 - 6x$

$= 2{x}^{2} + 6x - 216 = 0$

hence the required equation

i hope it will help u☺☺
