2x-1 less than -1 or -4x less than -12
Bond [772]

The solution to these equations is either x < 0 or x > 3.

In order to find them, we need to solve each equation separately. Let's start with the first one.

2x - 1 < -1 -----> Add 1 to both sides

2x < 0 -----> Now divide each side by 2.

x < 0

Now let's look at the second one.

-4x < -12 ----> Divide both sides by -4

x > 3 (Notice that the sign changes direction because we divided by a negative)

When you have an "or" statement, you'll wind up with two answers, so we use both of these.

P(x)= x^5-4x^4+3x^3+2x-6 <br> Use Descartes rule of signs to analyze the zeros
maxonik [38]
\bf \begin{array}{cccccccccccllll}&#10;P(x)= x^5&-&4x^4&+&3x^3&+&2x&-&6\\&#10;&yes&&yes&&\textit{no}&&yes&#10;\\\\\\&#10;P(-x)= -x^5&-&4x^4&-&3x^3&-&2x&-&6\\&#10;&\textit{no}&&\textit{no}&&\textit{no}&&\textit{no}&#10;\end{array}

notice where how many "yes" sign change happen in the positive "x"
and the on the negative "-x"

for the P(x) is 3 changes, thus
so is either 3 real positive ones, or 3-2 = 1 real positive one

P(-x) gives no sign changes, so there are 0 negative ones

the polynomial has a degree of 5, thus 5 roots
if it has 3 real positive ones, then it has 2 complex ones
the complex ones pick up the slack per se

if it has 1 real positive one, then it has 4 complex ones

bear in mind complex ones always come in pairs
