How do you factor, for example 6x^2+11x-10 ?
100,200,250,300,350,400,450,500,550,600,650,700,750,800,850, Are I think the factors...
You could just use the calculator or find out how to find factors on Google or something
I look for a 2 numbers that multiply to -60 and add to +11 but there arn't any so there are not rational roots.
I.e. you can factorise but there will be irrational numbers in there. This is not a normal thing to do.
If you want to do that you could use the quadratic formula or completing the squares method and work backwards from there.
