Factorise x2_2x+1
x2-6x+a
X2-18+81

x^2-2x+1 = (x-1)(x-1)

x^2-6x+a= (x-4)(x-2) a=8

X^2-18x+81 = (x-9)(x-9)

Step-by-step explanation:

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
