Consider the trinomial  x2  + 10x  + 16.which pair of numbers has a product of  ac  and a sum of  b? 2 and 52 and 84 and 4x 4 and 6what is the factored form of the trinomial? (x + 2)(x + 5)(x + 2)(x + 8)(x + 4)(x + 4)x (x + 4)(x + 6)

The coefficient of 10x and the last term 16 is what we'll focus on. Specifically just the numbers only (ignore the variable x for now).

Think of two numbers that both multiply to 16, and also add to 10. Those two numbers are 8 and 2 (in any order). You basically find this through trial and error.

8 + 2 = 10

8 * 2 = 16

So it factors to (x+8)(x+2). Since order of multiplication does not matter, this is the same as (x+2)(x+8)

the 3rd option is right
