To simplify the given expression (3x^2 - 2) + (11 - 5x), we need to combine like terms by adding or subtracting the coefficients of similar terms.
First, let's look at the terms with x^2. There is only one term with x^2, which is 3x^2.
Next, let's look at the terms with x. There is only one term with x, which is -5x.
Finally, let's look at the constants (numbers without variables). There are two constants, -2 and 11. We can simplify this as -2 + 11 = 9.
Putting it all together, the simplified expression is: 3x^2 - 5x + 9.
To simplify the expression (3x^2-2)+(11-5x), we can combine like terms.
First, let's simplify the terms inside the brackets:
3x^2-2 + 11-5x
Next, let's collect the like terms:
-5x + 3x^2 -2 + 11
Finally, combining the like terms we get:
3x^2 - 5x + 9
So, the simplified expression is 3x^2 - 5x + 9.
