20Simplifying Quadratic Expressions (A) Answers
Simplify each expression by combining like terms.
-7 + 4 - 5x - 7x² + 6x + 9x + 6x + 6x²
1.
= -x² + 16x - 3
1 - 3a² + 8a + 4a - 6a + 9a² + 9 + 6a
2.
= 6a² + 12a + 10
-5t² + 5t² - 6 - 8 - 5t + 8t + 2t² + 8t²
3.
= 10t² + 3t - 14
-r - 8r² + 6r + 6 + 3r² - 9r² + 9 - 8r²
4.
= -22r² + 5r + 15
5w² - 1 + 7w + 2w² + 5w² - w - 6w² - 8w
5.
= 6w² - 2w - 1
-8 - 3 - 2p² + 2p² - 5p - 2 - 5p + 9p²
6.
= 9p² - 10p - 13
8j² - 2j + j² + 1 + 7 + 2j + 5j² + j
7.
= 14j² + j + 8
-5k² - 7k² + 3k² - 3k² + 2k + 2k + 2k - 2k
8.
= -12k² + 4k
-8k² - 9 - 2k² + 6k + 9k² - k² - 3k - 7k
9.
= -2k² - 4k - 9
3d² + 8 - 4d + 4d² + 7d² + 8d² + 2d² - 4d
10.
= 24d² - 8d + 8
