[8.06] which polynomial is a perfect square trinomial?

49x2 − 28x + 16

4a2 − 20a + 25

25b2 − 20b − 16

16x2 − 24x − 9

Step-by-step explanation:

A binomial is called perfect square trinomial

if is satisfied.

For

a = 49, b = -28 and c = 16,

Thus, is not a perfect square trinomial.

For

a = 4, b = -20 and c = 25,

Thus, is a perfect square trinomial.

For

a = 25, b = -20 and c = -16,

Thus, is not a perfect square trinomial.

For

a = 16, b = -24 and c = -9,

Thus,   is not a perfect square trinomial.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
