g) (x + 9). (x + 13) =
h) (4x + 7) . (4x - 6) =
i) (x + 4)3 =
j) (x - 5)3 =

Answer 1

a) (X + 8)2 =

2x+8

b) (3x + 13)2 =

6x+26

c) (x - 2)2 =

2x-2

d) (9x - 5y)2 =

18x-10y

e) (x + 10). (x - 10) =

x²+10X-10X-100

x²-100

f) (15x + 11). (15x - 11) =

225x²-121

g) (x + 9). (x + 13) =

x²+9x+13x+117

x²+22x+117

h) (4x + 7) . (4x - 6) =

16x²+28x-24x-42

16x²+4x-42

i) (x + 4)3 =

3x+12

j) (x - 5)3 =

3x-15
