Which of the following binomials is a factor of x cubed plus 4 x squared plus x minus 6?
dusya [7]
The first thing we are going to do in this case is to rewrite the expression.
 We have then:
 x ^ 3 + 4x ^ 2 + x - 6
 Factoring the expression we have:
 (x-1) * (x + 2) * (x + 3)
 Therefore, we observe that the following binomial is a common factor:
 (x + 2)
 Answer:
 
B. x plus 2

Solve |p + 2| = 10Solve |p + 2| = 10<br><br> {-12}<br> {-8, 8}<br> {-12, 8}
valentinak56 [21]

By definition, we have

|p+2| = \begin{cases} p+2 &\text{ if } p+2 \geq 0 \\-p-2 &\text{ if } p+2 < 0 \end{cases}

So, we have to solve two different equations, depending of the possible range for the variable. We have to remember about these ranges when we decide to accept or discard the solutions:

Suppose that p+2\geq 0 \iff p \geq -2

In this case, the absolute value doesn't do anything: the equation is

p+2 = 10 \iff p = 10-2 = 8

We are supposing p \geq -2, so we can accept this solution.

Now, suppose that p+2 < 0 \iff p < -2. Now the sign of the expression is flipped by the absolute value, and the equation becomes

-p-2 = 10 \iff -p = 12 \iff p = -12

Again, the solution is coherent with the assumption, so we can accept this value as well.
