Find the value of k if x-1 is the factor of x ^ 2 + x + k

Ne4ueva [31]

Answer:

$k = -2$

Step-by-step explanation:

Recall from the Factor Theorem that if (x - a) is a factor of a polynomial P, then P(a) must equal 0.

Our polynomial is:

$\displaystyle P(x) = x^2 + x + k$

And we know that (x - 1) is a factor.

Therefore, by the Factor Theorem, P(1) must equal 0. Hence solve for k:

$\displaystyle \begin{aligned} P(1) = 0 & = (1)^2 + (1) + k \\ \\ 0 & = 2 + k \\ \\ k & = -2\end{aligned}$

In conclusion, the value of k is -2.

Find the measurements (the length L and the width W) of an inscribed rectangle under the line with the 1st quadrant of the x &am

Leni [432]

The question is incomplete. Here is the complete question.

Find the measurements (the lenght L and the width W) of an inscribed rectangle under the line y = - $\frac{3}{4}$ x + 3 with the 1st quadrant of the x & y coordinate system such that the area is maximum. Also, find that maximum area. To get full credit, you must draw the picture of the problem and label the length and the width in terms of x and y.
