Answer:
-4*(x^2) - 2*x + 6
Step-by-step explanation:
= 2x^2+(4x-6x^2)+9-(6x+3)
= 2*(x^2) + 4*x - 6*(x^2) + 9 - 6*x - 3
= 2*(x^2) - 6*(x^2) + 4*x - 6*x + 9 - 3
= -4*(x^2) - 2*x + 6
Answer:-4*(x^2) - 2*x + 6
Step-by-step explanation:
from both sides first
= 2x^2+(4x-6x^2)+9-(6x+3)
= 2*(x^2) + 4*x - 6*(x^2) + 9 - 6*x - 3
= 2*(x^2) - 6*(x^2) + 4*x - 6*x + 9 - 3
= -4*(x^2) - 2*x + 6
