How many ways can you factorise 24k + 16?
These rectangles have the same area but different length sides.
Give possible side lengths for each rectangle.
12ab + 6ab2
12ab + 6ab?
Compare answers with a partner.
12a'b + 6ab?
Use the rectangles to factorise the expressions.
a)
b)
4k
7x
7
a) Factorise 2 +l =
b) Use your understanding of factors to explain why there is no
integer, t, where
2h
t2 + t = 13
4k + 2h =
c) If t is an integer, explain why t +t = 14 has no solution
5
Factorise the expressions fully.
e) 42 - 12y =
b) 9m + 12 =
f) 16p + 24 =
d) If t is an integer, explain why t + t must be an even number.
c) 10y - 8 =
g) 6d – 6 =
d) 20 + 25x =
h) g? + 5g =
