Thank you so much!!!
Simplify the expression (0.4)3.
2. B. -2x^2-4x+12
3. A. -2x^2+2x+5
To simplify the given polynomials, combine like terms by adding or subtracting the coefficients of terms with the same variable and exponent.
Let's start with question 2:
2. 4x^2 + 4 - 5x + x - 2x^2 + 8
To simplify this polynomial, combine the terms with the same variable and exponent:
(4x^2 - 2x^2) + (4 - 5x + x) + 8
Combine the like terms within each set of parentheses:
2x^2 - 4x + 12
Therefore, the simplified form of the polynomial in question 2 is:
A. -2x^2 + 4x + 12
Now let's move on to question 3:
3. 3x^2 + 5x - 7x + 3 - 5x^2 + 2
Combine the terms with the same variable and exponent:
(3x^2 - 5x^2) + (5x - 7x) + (3 + 2)
Combine the like terms within each set of parentheses:
-2x^2 - 2x + 5
Therefore, the simplified form of the polynomial in question 3 is:
B. -2x^2 - 2x + 5
