Factor the Expression. If the expression cannot be factored, say so. 8.) x^2 - 4x - 12

soldier1979 [14.2K]

To factor an expression of the form:

$x^2+bx+c$

we find two numbers B and C that fulfills the following properties:

$\begin{gathered} B+C=b \\ BC=c \end{gathered}$

In this case we have b=-4 and c=-12. We can choose B=-6 and C=2. Then we write the expression as:

$x^2-4x-12=x^2-6x+2x-12$

and we factor the common factors in the first two and last terms:

$\begin{gathered} x^2-4x-12=x^2-6x+2x-12 \\ =x(x-6)+2(x-6) \\ =(x+2)(x-6) \end{gathered}$

Therefore:

$x^2-4x-12=(x+2)(x-6)$

The area of a storage shed floor is 20 ft2. The length is 3 more than twice the width. Find the dimensions of the storage shed f

vladimir1956 [14]

Answer:

2.5 ft wide
8 ft long

Step-by-step explanation:

The given relation between length and width can be used to write an expression for area. The equation setting that equal to the given area can be solved to find the shed dimensions.

<h3>Given relation</h3>

Let x represent the width of the shed. Then the length is (2x+3), and the area is ...

A = LW

20 = (2x+3)(x) . . . . . area of the shed

<h3>Solution</h3>

Completing the square gives ...

2x² +3x +1.125 = 21.125 . . . . . . add 2(9/16) to both sides

2(x +0.75)² = 21.125 . . . . . . . write as a square

x +0.75 = √10.5625 . . . . . divide by 2, take the square root

x = -0.75 +3.25 = 2.50 . . . . . subtract 0.75, keep the positive solution

The width of the shed is 2.5 feet; the length is 2(2.5)+3 = 8 feet.

300% = 45 x 3 = 135
45 + 135 = $180

180 x 0.8 = $144
