find the sum of $6x^2 - 2x$ and $2x^2 - 9x - 10$.
find the sum of $6x^2 - 2x$ and $2x^2 - 9x - 10$.
Answer
Explanation:
Step1: Write the sum expression
To find the sum of (6x^2 - 2x) and (2x^2 - 9x - 10), we write the expression as ((6x^2 - 2x)+(2x^2 - 9x - 10)).
Step2: Combine like terms
First, combine the (x^2) terms: (6x^2+2x^2 = 8x^2). Next, combine the (x) terms: (-2x-9x=-11x). The constant term is (-10) (since there is no constant term in the first polynomial, we just take the constant term from the second polynomial).
Putting it all together, we get (8x^2-11x - 10).
Answer:
(8x^2 - 11x - 10)
