Answer: -3x³ +2x² - x + 4

Step-by-step explanation:

Q(x) = -x³ + x² - x + 4
P(x) = 2x - 1
-x² * P(x) = -x²(2x - 1) = -2x³ + x²

Q(x) - x² * P(x)

= (-x³ + x² - x + 4) + (-2x³ + x²)

= -3x³ +2x² - x + 4

Answer:

c. -3x^3 + 2x^2 − x + 4

Step-by-step explanation:

given

P(x) = 2x -1

Q(x) = -x^3 + x^2 - x + 4

Q(x) -x^2 * P(x)

= -x^3 + x^2 - x + 4 - x^2*(2x - 1)

= -x^3 + x^2 - x + 4 - 2x^3 +x^2

= -3x^3 + 2x^2 - x + 4

ans is C

Answer: the expression 12f + 24 represents 12 times a quantity, added to 24.

Expplanation.

The expression 12f + 24 is an algebraic expression, especifically a first degree binomial; this is, a polynomial of two terms, whose maximum power is 1.

The algebraic expressions are used to represent word statements in mathematical language.

You can analyze each term of the expression and then tell what the total expresssion represents:

The first term 12f, where f is a variable with degree 1 (the exponent of the variable), represents the multiplication of a quantity (represented by the variable f) by 12.
