-24a^2 - 6a + 9
You don't want a negative in front of the variable that is being squared.
-1(24a^2 + 6a - 9)
-3(8a^2 + 2a - 3)
now we use the A C method. what two numbers multiply to equal A×C (8×-3) and add to be B (2)?
6 and -4
-3(8a^2 + 6a - 4a - 3) factor by grouping
-3(2a(4a + 3) -1(4a + 3))
-3(2a - 1)(4a + 3)
hope this helped C:
Answer:
First figure out what the whole shapes degrees will be then subtract 97 and 66 then divided it partially by 3 do get your answers for them
I got Y=12 for my answer.
Teresa had more points because since the fractions are not able to use you can see that 6 is larger than 5
