just checking if this is the right way to approach it:
the left one is degree three bc poi and right on is deg one, so degree four, so C.
i saw some use the turning point property?

did i do something stupid bc i solved it using the second method
but shouldnt there be two inequalities like the second like
i got 1-<x<1 and x<-1 x>-1/3 so u combine them
but the solution is diff
not sure what i did wrong

yeah thats weird, ur right

are u sure u didnt cut off the solution for the second one bc they have the right soln for the first method

WAIT SHIT I THOUGHT THIS WAS THE PROGRESS ONE AHAHAHAHA MY BADDDDD SORRY YALL

this might be a dumb qquestion but when they dot product it
why dont they like flip it so BA.BC bc the angle is from point B yeah
But they still do AB.CB which is like them facing each other but i was taught the vectors need to face away
the answer u get is still the same but i was just wondering if that is ok to do if they are facing each other
mathematically it works bc BA is just negative AB so it cancels out anyways but like in terms of like working out yk?
(dont mine the solutions idk why they uploaded it upside down )
