Question

One solution of the equation 2x^2 - x - 10 = 0 is 5/2 . What is the other solution

Answer 1

you could solve this using multiple meathods, one of them is using the quadratic equation
\[(-(-1)\pm \sqrt{(-1)^2-4(2)(-10)})/2(2)\]
if you simplify this, you get
\[(1\pm \sqrt{(1)-(-80)})/4\]
and this becomes
\[(1\pm9)/4\]
this is simplified to 10/4 or 5/2 and 8/4 or 2
so the other solution is 2

Answer 2

i apologize i was incorrect

Answer 3

it would be -8/4 or -2
the answer is -2
