How to solve 1+x+x^2

Ksju [112]

There is no way to simplify this further, if that’s what your asking. If you are asking to the answer to the equation, I will need to know the value of x.

25. The width of a rectangle is (x+1) and the length is (X-6). What is the length and width of the rectangle if the area is

Elis [28]

Answer:

x=−4 or x=9

Step-by-step explanation:

1- As we know the formula for Area of rectangle = length x width

2- Multiply given width = (x+1) with length = (x-6)

3-Equation will be (x+1)(x-6) = 30

4- Solving x^2−5 x−6 = 30

5- x^2−5 x -36 = 0

6-Factor left side of equation.

(x+4)(x−9)=0

Set factors equal to 0.

x+4=0 or x−9=0

Answer:

C) p(x) has a zero between x=2 and x=4

Step-by-step explanation:

For a polynomial p(x), $p(a)=R$ means that, when p(x) is divided by $x-a$ , the remainder is $R$ .

This is called the remainder theorem

Therefore $p(2)=1$ , $p(4)=-1$ means that when p(x) is divided $x-2$ and $x-4$ is 1 and $-1$ respectively.

Also the Intermediate value theorem says that, if p(a) and p(b) have opposite signs then there is a certain $c$ on $(a,b)$ where $f(c)=0$ i.e there is a zero between $a$ and $b$
