Answer:
3 (4 a - 3)
Step-by-step explanation:
Simplify the following:
3 a (3 - a) + 3 (a^2 - 3) + 3 a
3 a (3 - a) = 9 a - 3 a^2:
9 a - 3 a^2 + 3 (a^2 - 3) + 3 a
3 (a^2 - 3) = 3 a^2 - 9:
3 a^2 - 9 - 3 a^2 + 9 a + 3 a
Grouping like terms, 3 a^2 - 3 a^2 + 9 a + 3 a - 9 = (9 a + 3 a) - 9 + (-3 a^2 + 3 a^2):
(9 a + 3 a) - 9 + (-3 a^2 + 3 a^2)
9 a + 3 a = 12 a:
12 a - 9 + (-3 a^2 + 3 a^2)
3 a^2 - 3 a^2 = 0:
12 a - 9
Factor 3 out of 12 a - 9:
Answer: 3 (4 a - 3)
12a−9
Distribute:
=(3a)(3)+(3a)(−a)+(3)(a2)+(3)(−3)+3a
=9a+−3a2+3a2+−9+3a
Combine Like Terms:
=(−3a2+3a2)+(9a+3a)+(−9)
=12a+−9

Hope this helps and have a nice day
That is good! Just plug them in the graph and you should be good. Also this should be a parabola correct?
-2x+2y+3z=0
-2x-y+z=-3
2x+3y+3z=5

---------------- Subtract
3y + 2z = 3 Eqn A
=========================
---------------- Add
2y + 4z = 2
6y + 4z = 6 Eqn A times 2
------------------------------------ Subtract
-4y = -4
y = 1
