20Simplifying Quadratic Expressions (C) Answers
Simplify each expression by combining like terms.
-4y² + y + 4y² + 3y² - 6 + 8y - 9y + 5y
1.
= 3y² + 5y - 6
-4g² - 1 + 4g - g + 7g² + 4g + 5 + 4g
2.
= 3g² + 11g + 4
3 - 5n - 5n² + 2n - 2n² - 8n - 5n - 4n²
3.
= -11n² - 16n + 3
-z² + 5z + 4z² - 6z² - 8z - 4z - 9 + 8z²
4.
= 5z² - 7z - 9
-2 - 4z - 9z² + 4 + 3z + 3z² + 7z² + 9z²
5.
= 10z² - z + 2
-3c² + 6 - c - 4c² + c² - c² - 5c² - 1
6.
= -12c² - c + 5
5r - 4r² + 8 + 3r + 7r² + 6r² - r² - 6r²
7.
= 2r² + 8r + 8
1 - 9m² - 3m² - 8 + m + 5m² - 4m² - 2
8.
= -11m² + m - 9
9j - 7j + 8 + 2j² + 3j² + 7j² - j - 6j²
9.
= 6j² + j + 8
-2d + 9d + 2d² + 5d² - 4d² - 9d² + 8d² + 9
10.
= 2d² + 7d + 9
