what two numbers will add up to 19 but when multiplied will give 60 (coefficient of x^2 times 10[c])?

15 and 4!

Plug those in:
6x^2 + 4x + 15x + 10
Now you can factorise easily.

The answer will be:
(2x+5)(3x+2)

in case you're putting forward destructive six situations 2 plus nineteen situations x minus ten then this expression could nicely be simplified to -12+19x-10 and could be extra simplified to -2+19x or 19x-2

(3x + 2)(2x + 5)
PS
Good luck in exam-----keep calm !

6x^2 + 19x + 10
= (2x + 5)(3x + 2)
