Here is a table of values for y=1+2x-x^2

a) Copy and complete the table (DONE)
b) Draw the graph of y=1+2x-x^2 (DONE)
c) By drawing a suitable line on your graph, solve the equation 2+4x-2x^2=2-2x

I know that part c is asking me to rearrange but How would I rearrange that

I got 1+2x-x^2=1-4x+x^2 when I tried to rearrange it but I'm sure that this is wrong because it isn't a line

So what do I need to do in order to solve part c?

Suppose you just have to see it - take a factor of 2 out of both sides of the equation. That should help

So

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

And from there on what do I do?

Divide both sides by two

And then draw the line of 1-x right?

Yep
