Question

resolver bhaskara

x² + 7x + 12 = 0

Answer 1

olá !!!

$x^{2} +7x+12=0\\\\a=1; b=7; c=12\\\\\Delta =b^{2} -4ac \gg \Delta =(-7)^{2} -4 *1*12 \gg \Delta =49 - 48 \gg \Delta =1\\\\x'\neq x''\\\\x=\frac{b \pm\sqrt{\Delta } }{2a} \gg x=\frac{-(-7)\pm\sqrt{1} }{2*1a} \gg x=\frac{7 \pm 1}{2} \gg\\\\x'=\frac{7\pm1}{2} \gg x'=\frac{8}{2} \gg x'=4\\\\x"=\frac{7-1}{2} \gg x"=\frac{6}{2} \gg x"=3\\\\[S=3;4]$

espero ter ajudado
