Answer 1

Answer:

Hey mate here is your answer:

____________________________________

→$x^2+6x-10=0.$

We know that:

→$x=\frac{-b+-\sqrt{b^2-4ac} }{2a},$

∴,

→$x=\frac{-6+-\sqrt{6^2-4*1*-10} }{2*1},$

→$x=\frac{-6+-\sqrt{36+40} }{2}$,

→$x=\frac{-6+-\sqrt{76} }{2}$,

→$x=\frac{-6+-\sqrt{19*4} }{2}$,

→$x=\frac{-6+-2\sqrt{19} }{2}$,

→→→$x=3+-\sqrt{19}.$ or 3±√19 is the answer.(+- means ± only).
