Question

3x2 - 13× 10= 0 por formula general

Answer 1

$3 x^{2} -13x+10= 0 \\ \\{ Formula General: \boxed{ x=\dfrac{-b\pm \sqrt{b ^{2}-4ac } }{2a}} \\ \\ {Necesitamos saber: \\ \\ a= 3 \\ b= -13\\ c= 10 \\ \\ \boxed{ x=\dfrac{-(-13)\pm \sqrt{(-13) ^{2}-4(3)(10) } }{2(3)}}$

$\boxed{ x=\dfrac{13\pm \sqrt{169-120 } }{6}} \\ \\ \\ \boxed{ x=\dfrac{13\pm \sqrt{49 } }{6}} \\ \\ \\ \boxed{ x=\dfrac{13\pm 7 }{6}} \\ \\ \\ \boxed{ x _{1} =\dfrac{13+ 7 }{6}} \\ \\ \\ \boxed{ x _{1} =\dfrac{20 }{6}}$

$\boxed{ x _{2} =\dfrac{13-7 }{6}} \\ \\ \\ \boxed{ x _{2} =\dfrac{6 }{6}}$

$\boxed{ x _{2} =1 \ }}$

Respuestas:

$\boxed{ x _{1} =\dfrac{20 }{6}} \\ \\ \\\boxed{ x _{2} =1}$

Saludos Y suerte!!
