Simplifying the Expression: (a^2 - 4a + 6) + (-3a^2 + 13a + 1)
To simplify the expression (a^2 - 4a + 6) + (-3a^2 + 13a + 1), we can follow these steps:
-
Remove the parentheses: Since we are adding the two expressions, the parentheses don't affect the order of operations. We can simply rewrite the expression as:
a^2 - 4a + 6 - 3a^2 + 13a + 1
-
Combine like terms: Identify terms with the same variable and exponent. In this case, we have:
- a^2 terms: a^2 - 3a^2
- a terms: -4a + 13a
- Constant terms: 6 + 1
-
Simplify each group of terms:
- a^2 - 3a^2 = -2a^2
- -4a + 13a = 9a
- 6 + 1 = 7
-
Combine the simplified terms:
-2a^2 + 9a + 7
Therefore, the simplified form of the expression (a^2 - 4a + 6) + (-3a^2 + 13a + 1) is -2a^2 + 9a + 7.
