20Simplifying Quadratic Expressions (I) Answers
Simplify each expression by combining like terms.
8 - d - 2d² + 7d² + 3d² + 4d - 2d² - 8d²
1.
= -2d² + 3d + 8
-2m² + 7 - 1 + 7 + 2m + 9m² + 2m² + 2m²
2.
= 11m² + 2m + 13
-1 - 6w - 8w - 5w² - 5 + 2 + 3w + 9
3.
= -5w² - 11w + 5
9 + 5k + 9k² - 6k² + 9 - k + 2k + 7
4.
= 3k² + 6k + 25
-3v + 5 + 4v + 6 + 2v² - 4v² + 7v + 2
5.
= -2v² + 8v + 13
-5x + 5x² - 2x + 5 + x² + 9x² + 5 + 2x²
6.
= 17x² - 7x + 10
-7t² + 3t² - 2t² + 2 + 2t - 3 - 7t² - 4t²
7.
= -17t² + 2t - 1
-7y - 7y - 3 + 8y² - 9y - 7y - 5y² - 7y
8.
= 3y² - 37y - 3
3j - 9j² + 9 + 1 - 7j² + j² + 1 + 7
9.
= -15j² + 3j + 18
-v + 2 + 5 - 7v² + 3v + 5v + 9v² - 8
10.
= 2v² + 7v - 1
