y = a(x + 16)(x + 2)

72 = a(-18 + 16)(-18 + 2)

72 = a(-2)(-16)

72 = a(32)

\frac{72}{32} = a

\frac{9}{4} = a

Answer: y = \frac{9}{4}(x + 16)(x + 2)

Select the two binomials that are factors of this trinomial x2+10x+16
Zigmanuir [339]

So for this trinomial, I will be factoring by grouping. Firstly, what two terms have a product of 16x^2 and a sum of 10x? That would be 8x and 2x. Replace 10x with 2x + 8x:

x^2+2x+8x+16

Next, factor x^2 + 2x and 8x + 16 separately. Make sure that they have the same quantity inside the parentheses: x(x+2)+8(x+2)

<u>Now you can rewrite this as (x+8)(x+2) , which is your final answer.</u>
