Since this can’t be factored easily, you have to use synthetic division. This makes the answer x+4+(-1/x+5)
Answer:
Step-by-step explanation:
please note -2 is not a zero ,it should be 2 is a zero.
by synthetic division
2| 1 4 -10 -4
| 2 12 4
|----------------
1 6 2 | 0
x²+6x+2=0

Let x and y be the length and width of the rectangle respectively
2(x+y)=32...(1)
x=2y-5...(2)
From (1),we have
2x+2y=32...(3)
By sub.(2) into (3),we have
2(2y-5)+2y=32
4y-10+2y=32
6y=42
y=7
By sub.y=7 into (2),we have
x=2*7-5
x=14-5
x=9
Length =9m
Width =7m
