I'm having trouble with polynomials and adding them...(for some reason) How would I do this problem...
(5a - 3asquared) - (-6a - 6)
(5a - 3a^2) - (-6a - 6) =
Multiply second parenthesis by -1.
5a - 3a^2 + 6a + 6 =
Combine like terms.
-3a^2 +11a + 6
To add polynomials, you need to combine like terms. Here's a step-by-step breakdown of how to add the polynomials:
1. Start by removing the parentheses and distributing the negative sign (-) to both terms inside the second set of parentheses:
(5a - 3asquared) - (-6a - 6)
= 5a - 3asquared + 6a + 6
Now, we have four terms to combine.
2. Combine the like terms by adding or subtracting the coefficients of each term that has the same variable raised to the same power:
(5a + 6a) + (-3asquared) + 6
= 11a - 3asquared + 6
That's it! The sum of the polynomials is 11a - 3asquared + 6.
