Respuesta:
X = 35+8[tex]\sqrt{19}[/tex], X = 35-8[tex]\sqrt{19}[/tex]
Explicación paso a paso:
x1, 2 = -(-70) + [tex]\sqrt{(-70)2 -4(1)(9)}[/tex] /2(1)
x1, 2 = -(-70) + 16[tex]\sqrt{19}[/tex] /2(1)
X1 =-(-70) + 16[tex]\sqrt{19}[/tex] /2(1) X2 =-(-70) -16 [tex]\sqrt{19}[/tex] /2(1)
X1= 35 + 8 [tex]\sqrt{19}[/tex], X2= 35 - 8 [tex]\sqrt{19}[/tex]
