You start off by multiplying the second bracket by -1 to get rid of the bracket.
So,
(2x3 + x2 - 4x) - 9x3 + 3x2 =
2x3 +x2 - 4x - 9x3 + 3x2 =
(2x3 - 9x3) + (x2 + 3x2) - 4x =
-7x3 + 4x2 - 4x
-3 would be before the zero and the point would be on the 3.3 on the line
Answer:
Step-by-step explanation:
Zero property because you are using zeros to multiply
You could write this by going 63+42 or add 63 and 42
