Brut [27]

Answer:

The answer to your question is the letter B. P(3) = -6

Step-by-step explanation:

                                     4t²- 5t -1

                           t - 3   4t³ - 17t² + 14t - 3

                                   -4t³  +12t²

                                     0    -5t² +14t

                                           +5t² -15t

                                             0    - t   - 3

                                                   +t   -3

                                                     0   -6

Quotient = 4t² - 5t - 1

Remainder = -6

The remainder is constant it always be -6

P(3) = 4(3)³ - 17(3)² + 14(3) - 3

       = 4(27) - 17(9) + 42 - 3

       = 108 - 153 + 42 - 3

       = 150 - 156

      = -6

What is a factor of X2–9 X +14
Taya2010 [7]

The factors of the expression x^2 - 9x + 14 are (x - 7) and (x - 2)

<h3>How to factor the expression?</h3>

The expression is given as:

x^2 - 9x + 14

Expand

x^2 - 2x - 7x + 14

Factorize the expression

x(x - 2) - 7(x - 2)

Factor out x - 2 from the expression

(x - 7)(x - 2)'

Hence, the factorized expression of x^2 - 9x + 14 is (x - 7)(x - 2)'
