drag the tiles to the boxes to form correct pairs. not all tiles will be used.

match the perfect square trinomials with their factors.

Factor the Polynomials given to find the correct factors.

See attached picture for the answers.

Step-by-step explanation:

1). 4a² + 4a + 1

= (2a)² + 2(2a) + 1² [Since x² + y² + 2xy = (x + y)(x + y)]

= (2a + 1)²

= (2a + 1)(2a + 1)

2). 4a² - 4a + 1

= (2a)² - 2(2a) + 1² [ Since x² - 2xy + y² = (x - y)²]

= (2a - 1)(2a - 1)

3). 4 - 4a + a²

= a² - 4a + 4 [ since x² - 2x + y² = (x - y)²]

= (a - 2)²

= (a - 2)(a - 2) ≈ (2 - a)(2 - a)

4). 4 + 4a + a² [Since x² + y² + 2xy = (x + y)(x + y)]

= (a + 2)²

= (a + 2)(a +2)

other answer is correct. i had used the radius of the radius somehow. a website:
