Question 24
Length of rectangle = ( 6 x−29 )
Width of rectangle ¿ ( 5 x−17 )
Perimeter of rectangle plot =?
Perimeter of rectangle plot ¿ 2(Length+ Width)
¿ 2 { ( 6 x−29 ) + ( 5 x−17 ) }
¿ 2 ( 11 x−46 )
¿ 22 x−92
Question 25
2 x2 −15 x +7
¿ 2 x2 − ( 14 x+ x ) +7
¿ 2 x2 −14 x−x+ 7
¿ 2 x ( x−7 )−1 ( x −7 )
¿ ( x−7 ) ( 2 x−1 )
Question 26
f ( n )=n3 −2 n2+ 4 n−8
Factor n2 from the first two terms and factor 4 from the last 2 terms.
f ( n )=n2 ( n−2 )+ 4 ( n−2 )
You now have two terms both containing a factor of (n−2). Factor(n−2) from both of these
terms.
f ( n )= ( n−2 ) ( n2 +4 )
