Answer:

<em><u>A</u></em>

f(x) = 3x - 2 \\ g(x) = 2x + 1 \\ (f - g)x = f(x) - g(x) \\  = (3x - 2) - (2x + 1) \\  = (3 - 2)x + ( - 2 - 1) \\  = x - 3

Answer:

A

Step-by-step explanation:

= f(x) - g(x)

= 3x - 2 - (2x + 1)

= 3x - 2 - 2x - 1 ← collect like terms

= x - 3 → A

18) The degree of P(x) = (x-1)(x+2)(x+3)(2x-5) is<br><br><br>4<br>3<br>2<br>1​
Fantom [35]

Answer:

degree 4

Step-by-step explanation:

The degree of a polynomial is determined by the term with the largest exponent for the polynomial in standard form

Given

P(x) = (x - 1)(x + 2)(x + 3)(2x - 5)

We need only consider the product of the leading terms in each factor, that is

x(x)(x)(2x) = 2x^{4} ← is the leading term in the expansion of the factors

with exponent 4

Thus polynomial is of degree 4
