Help quick please give an explanation too.

1 answer:

4 0

Answer: (x+2)*(x-4)*(x+21) = 0 has "many" solutions

Step-by-step explanation: (x+2) = 0 only has one solution.

(x+2)*(x-4) = 0 has two solutions, -2 and 4

(x+2)*(x-4)*(x+21) = 0 has three solutions, -2, 4, and -21, etc

If "many" means more than three, then add another (x+XX) term. A quadratic equation generally has two solutions.

Answer:

The answer to your question is: -9y³ - 3y² + 5y - 9

Step-by-step explanation:

( y² - 3y³ - 2 + 5y ) - (7 + 8y² - 4y² + 6y³)

y² - 3y³ - 2 + 5y - 7 - 8y² + 4y² - 6y³

Like terms -3y³ - 6y³ + y² - 8y² + 4y² + 5y - 2 - 7

-9y³ - 3y² + 5y - 9

First, distribute the 3 to the parentheses.
2x + 16 = 3x - 27
Add 27 to the left.
2x + 43 = 3x
Subtract 2x to the right.
43 = x
