Answer:

(f·g)(x) = x³ -8x² +20x -16

Step-by-step explanation:

The distributive property is useful for this.

(f·g)(x) = f(x)·g(x) = (x² -6x +8)(x -2)

= x(x² -6x +8) -2(x² -6x +8)

= x³ -6x² +8x -2x² +12x -16

(f·g)(x) = x³ -8x² +20x -16

Additional comment

I find it convenient to separate the terms of the shortest polynomial. That way, the distributive property doesn't need to be used quite so many times. Of course, any outside minus sign applies to all terms inside parentheses.

Answer:

Length 7 feet and Width 5 feet

Step-by-step explanation:

we know that

The area of the rectangle ( a dining room table) is equal to

$A=LW$

where

$L=(3x+1)\ ft$

$W=(3x-1)\ ft$

$A=35\ ft^2$

substitute

$35=(3x+1)(3x-1)$

Apply difference of squares right side

$35=9x^2-1$

$9x^2=36\\x^2=4\\x=\pm2$

Remember that the length cannot be a negative number

x=2

Find the length

$L=(3(2)+1)=7\ ft$

Find the width

$W=(3(2)-1)=5\ ft$
