Answer 1

Step-by-step explanation:

1)

common factor = 3ab

2)

d. (x+a) (x+b)

3m²+9m+6

3(m²+3m+2)

3(m²+2m+1m+2)

3{m(m+2)+1(m+2)}

3(m+2)(m+1)

(3m+6)(3m+3)

3)

(7x+7x²)/7x =x

LHS= (7x+7x²)/7x

= 7x(1+x) /7x

= 1+x

RHS = x

so this is wrong and the error

4)

p²-9p= -5

p²-9p+5=0

this cannot be factorized
