c) 5x-5
d)ax-ay
e)y²+6y
g) 4x-7x²
h)m-m
i)a+a
j)x²+13x
k)5m-m²
l)x+x
m)8x-12x
n)15x-21x²

Answer 1

c)

= 5x - 5

= 5.(x - 1)

***********************
d)
= ax - ay

= a(x - y)

**********************
e)
= y² + 6y

= y.(y + 6)

*********************
g)
= 4x - 7x²

= x.(4 - 7x)

*********************************
h)
m - m = 0

**********************
i)
a + a = 2a

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
j)
= x² + 13x

= x.(x + 13)

***********************
k)

= 5m - m²

= m.(5 - m)

*************************
l)
x + x = 2x

**********************
m)
8x - 12x = - 12x + 8x = - 4x

***************************
n) 

= 15x - 21x²

= 3x.(5 - 7x)
