Carter divided the polynomial 6x2 + 4x + 3 by the monomial 2x using long division, and got an answer of 3x + 2 + . His work is s
Gnesinka [82]

Answer:

C. Both Carter and Demi are correct and would get the same answer.

Step-by-step explanation:

Here, the given polynomial is : P(x) =6x^2 + 4x + 3

The given monomial : Q(x)  = 2 x

Now, according to the given question:

Dividend = P(x), Divisor  = Q(x)

Now, Carter divide P(x) by Q (x) with LONG DIVISION METHOD.

If we divide P(x) by Q(x) by Long division, we get:

\frac{P(x)}{Q(x)}  = \frac{(6x^2 + 4x + 3)}{(2x)}  = 3x +  2 + \frac{3}{2} x = R(x)

Also, if Demi divides each term of P(x) by The given monomial (2x) , we get:

\frac{P(x)}{Q(x)}  = \frac{(6x^2 + 4x + 3)}{(2x)}  = \frac{6x^2}{2x}  + \frac{4x}{2x} +\frac{3}{2x} \\= 3x +  2 + \frac{3}{2}  = R(x)

⇒In both the case, R(X)Quotient is SAME.

Hence, Both Carter and Demi are correct and would get the same answer.

Which of the binomials below is a factor of this trinomial ? X^2 + x + 12
PolarNik [594]
That trinomial can't be factored. You would have to complete the square to factor it and even then your answer would be an imaginary number. 

x² + x + 12 = 0
x² + x = - 12
x² + x + 1/4 = - 12 + 1/4
x² + x + 1/4 = - 11 3/4
x² + x + 1/4 = - 47/4

(x + 1/2)² = - 47/4 
x + 1/2 = +/- √(- 47/4) 
x + 1/2 = +/- \frac{47}{4}i

x = 1/2 +/- \frac{47}{4}i

If the constant was a negative, it would be factor-able (is that a word?).
