What are the solutions of a quadratic equation (x-8)2-13(x-8)+30=0

For know, just set x-8=y. You have the equation

Solving for y, you get (y-10)(y-3)=0. So, y=10 and y=3.

But we need to add 8 each each because we are solving for x, not y.

So, x=18 and x=11 are your answers.

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

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
