1.2x4(4x2 + 3x + 1)
2.(4x – 3)(2x2 – 7x + 1)
3.(x2 + 4x – 3)(2x2 + x + 6)

4.Write a simplified polynomial expression to represent the area of the rectangle below

5.Write a simplified polynomial expression to represent the area of the square tile, shown below.

Answer 1

----> 2x4(4x2 + 3x + 1)
8x^6+6x^5+2x^4
---->(4x - 3)(2x2 - 7x + 1)
8x^3-28x^2+4x-6x^2+21x-3 = 8x^3-34x^2+25x-3
---->(x2 + 4x - 3)(2x2 + x + 6)
2x^4+x^3+6x^2+8x^3+4x^2+24x-6x^2-3x-18 = 2x^4+9x^3+4x^2+21x-18
---->(x - 2)(x - 3)
x^2-3x-2x+6 = x^2-5x+6
