Try this:
x³+4x²+x-6=0
1) To re-write the equation into form:
1*x³+4*x²+1*x-6=0, the note 1+4+1=6, it means x=1
2) to re-write the equation into form:
(x-1)(x²+5x+6)=0
(x-1)(x+2)(x+3)=0
3)
$\left[\begin{array}{ccc}x-1=0\\x+2=0\\x+3=0\end{array}\right \ \ \textless \ =\ \textgreater \ \left[\begin{array}{ccc}x=1\\x=-2\\x=-3\end{array}\right$
Answer: -3;-2;1.

The Mazurskys decide to retile their mud room in 18 in. by 18 in. tiles. If their mudroom is 5 ft 6 in. by 13 ft, how many tiles

Mrac [35]

The area of one tile is 18 x 18 = 324 square inches.

Convert the dimensions of the room into inches:

5 ft 6 in. = 66 inches.

13 ft = 156 inches.

The area of the room is: 156 x 66 = 10296 square inches.

To find the number of tiles needed, divide the total area of the room by the area of one tile:

10,296 / 324 = 31.78, which means they will need 32 tiles.
