Which polynomial can be simplified to a difference of squares?

10a2 + 3a – 3a – 16
16a2 – 4a + 4a – 1
25a2 + 6a – 6a + 36
24a2 – 9a + 9a + 4

It's B on Edge

Hope this helps!!

Step-by-step explanation:

the answer is 16a2-4a+4a-1

it can be simplified to 16a2-1, which can be factored to

(4a+1)(4a-1)

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
