Which products result in a perfect square trinomial? Select three options.

1). (-x + 9)(-x - 9)

2). (xy + x)(xy + x)

3). (2x - 3)(-3 + 2x)

4). (16 - x²)(x²+ 16)

5). (4y² + 25)(25 + 4y²)

Option (1),

(-x + 9)(-x - 9) = -(-x + 9)(x + 9)

Therefore, product is not a perfect square.

Option (2)

(xy + x)(xy + x) = (xy + x)²

So the product is a perfect square trinomial.

Option (3)

(2x - 3)(-3 + 2x) = (2x - 3)²

Therefore, product is a perfect square trinomial.

Option (4)

(16 - x²)(x²+ 16) = (-x⁴+ 256)

Therefore, product is not a trinomial.

Option (5)

(4y² + 25)(25 + 4y²) = (4y² + 25)²

                                = 16y⁴ + 200y² + 625

Therefore, product is a perfect square trinomial.

Options (2), (3) and (5) are the correct options.

it 2

step-by-step explanation:

8^1/3=2

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
