We have 
$$(10x^2 - 5) - (3x^2 - 2x + 7)$$
Let's open the brackets first being mindful that the second term has a '  - 'sign  before it
$$10x^2-5-3x^2+2x-7$$
Let's bring the like terms together
$$10x^2-3x^2+2x-5-7$$
Now we'll combine the like terms
$$x^2(10-3)+2x-5-7$$
Simplifying now, we get finlly
$$7x^2+2x-12$$
