Answer 1

OI...

$x^2-11x+24=0\\\\Coeficientes:\;a=1,\;b=-11\;e\;c=24\\\\\Delta=b^2-4ac\\\Delta=-11^2-4\cdot1\cdot24\\\Delta=121-96\\\Delta=25\\\\x=\dfrac{-b\pm\sqrt{\Delta}}{2a}\\\\x=\dfrac{11\pm\sqrt{25}}{2\cdot1}\\\\x=\dfrac{11\pm5}{2}\\\\x_1=\dfrac{11+5}{2}=\dfrac{16}{2}=8\\\\x_2=\dfrac{11-5}{2}=\dfrac{6}{2}=3$
