Use synthetic division to find the result when 2x3 + x2 + x – 4 is divided by
X – 1.

2x² + 3x + 4

Step-by-step explanation:

Using synthetic division to divide by x - 1

  1 |   2   1   1   - 4

        ↓   2  3    4

         2  3   4   0 ← remainder = 0

            ↑ quotient

quotient = 2x² + 3x + 4

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
