20Simplifying Quadratic Expressions (I) Answers
Simplify each expression by combining like terms.
6z² - 8z - 4z² - 5 + 7z² - 3 + 7z - 4 + 9 - 9z²
1.
= -z - 3
9a - 7a + 3a + 5a² + 4a² + 4 - 4a - 7a - 4a² - 6
2.
= 5a² - 6a - 2
4v² - 2 + 9v² + 6v² + 4 - 4v - v² + 7v + 3v + 3
3.
= 18v² + 6v + 5
6y + y - 9y - 8y + 2y² - 7y + 1 + 4y² + 9y² - 8y²
4.
= 7y² - 17y + 1
8z - 5z + 3 + 9z² + 6z² - 3z - 8z² + 5z² + 4z - 5z
5.
= 12z² - z + 3
-9f - 4f² + f² + 8f² + 5 - 9f² - 4f² - 8f² + 5 + 1
6.
= -16f² - 9f + 11
8b - 4b² - 4 - 5b + b² + b² + 3b² - 6b + 8 + 3b
7.
= b² + 4
5z² - 8z + 3z² + 6z² + 8 + 5z² - 5z - 9z² + 7z + z²
8.
= 11z² - 6z + 8
9 + 3 + 5 + 6b + 9b² - 1 + 9b² - b - 6b² - 7
9.
= 12b² + 5b + 9
5 - 3w² - w + 7w - 4w² + 7w² + 3w² + 9w - w² - 4
10.
= 2w² + 15w + 1
