Is synthetic division the same as polynomial division?
Elena-2011 [213]

The synthetic division is not same as the polynomial long division.

Given:

Let's take a polynomial function f(x) = x^3+2x^2-5x-6 divided by x-2.

Using synthetic divison:

2    1     2     -5     -6

     0    2      8      6

     1     4      3      0

(x-2)(x^2+4x+3)

= (x-2)(x+3)(x+1)

Polynomial long division:

x-2)x^3+2x^2-5x-6 (x^2+4x+3

     x^3- 2x^2

            4x^2 - 5x + 6

            4x^2 - 8x

                       3x + 6

                       3x - 6

                         0

=(x-2)(x^2+4x+3)

Need help with third question!!!!!!!!!!
Leokris [45]

Answer:

1.

  • Angle 2 = Angle 4 (alternate angles)
  • Angle 1 = Angle 5 (corresponding angles)

2.

Angle 1 + Angle 2 + Angle 3 = 180 (angles on a line)

Now,

Angle 2 = Angle 4 (alternate angles)

and Angle 1 = Angle 5 (corresponding angles)

So,

Angle 1 + Angle 2 + Angle 3 = Angle 5 + Angle 4 + Angle 3 = 180

Hence proved

Step-by-step explanation:
