20Simplifying Quadratic Expressions (A) Answers
Simplify each expression by combining like terms.
-8 - 9 + 9s² + 9s² - 3s - 5 - 1 + 7s² + 9 + 4s
1.
= 25s² + s - 14
-5z - 8z² + 2z² - 4z + 9z + 7z² + 1 - z + 6z² - 5
2.
= 7z² - z - 4
2n² - 2n + 7n² - 1 + 9n² + 6n² - 4n + 5n² - 2 - 1
3.
= 29n² - 6n - 4
-9 + 8q² + 8 - 8q - 7q² + 5q - q² + 2q + 3q + 3q²
4.
= 3q² + 2q - 1
6q - 8q² - 7q - 9q² + 2 - q² - q² - 8q - 2q² + 8q
5.
= -21q² - q + 2
6q² + 7q - 5q² - 4q² + 8q² + 6q + 3q² - 4q + 5 - 4
6.
= 8q² + 9q + 1
4 + 6v² - 8v² - 5v² + 5v² + 3v² + 5 + 8 - 6v² - 2v
7.
= -5v² - 2v + 17
f² - 7f + 5f + 8f² + 7f² - 5f + 9f + 5f - 3 - 7
8.
= 16f² + 7f - 10
-8z - 7z² - 5 + 7z + 5 + 7z² - 2z² + 5 + 3z² - 4z²
9.
= -3z² - z + 5
-3 + 3 + 3 + 2 + 8f + 2f² - 5f + 9 - 9f + 3f²
10.
= 5f² - 6f + 14
