Group terms that have factorable coefficients (like 2&4 and then 9&18)
(4x³ + 2x²) + (-18x - 9)
factor out the like terms
2x²(2x + 1) - 9(2x +1)
parenthesis are the same so you can factor further.. {Like 2x+3x = (2+3)x}
(2x² - 9)(2x+1)
Factored too far they only want Answer C. is the correct one for grouping
Answer:
3
Step-by-step explanation:
We want to cancel out the 3y. The second equation has a -y so if we multiply that by 3 we'll get -3y and when we add the ys go away.

Answer:
A and D
Step-by-step explanation:
Either rotate the dilated circle 180° about point C or Translate the dilated circle so that it's centre is at point B so that we come to know that the circles are similar
