Idon’t understand how to get to the answer and simply. it’s d on the sheet btw

That's looks hard I have a go but I don't know what to do with that the dot in the middle of that. Sorry if it's wrong. Hopefully That helps ❤
12x-18= 6(2x−3)
X^2 - 2x - 15= (x+3)(x−5)
So the second one would be:
X^2-x-12= (x+3)(x−4)
3x^2-9x-12= 3(x+1)(x−4)
Then would you ÷ it?
So the first one :
6(2x−3) ÷ (x+3)(x−5) = 12x2−78x+90

X+3
Then the second one:
(x+3)(x−4) ÷ 3(x+1)(x−4) =

1. -4. -13 40
-- x4+ x^3 + x^2 + x + 16
3. 3. 3. 3

step-by-step explanation:

when the line is solid:

it's either < or >

when the line is dashed:

it's either < or >

this > inequality sign means:

greater thanmore thanaboveexceeds

this < inequality sign means:

less thanfewer thanbelow

this > inequality sign means:

greater than/equal tono less thanat leastminimum of

this < inequality sign means:

less than/equal tono more thanat mostmaximum of

about the problem:

since the line is solid, that means it's either < or >

srry i'm not done ! i'll
