Answer:

2x + 7

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

f(x) - g(x) = 3x + 1 - (x - 6) = 3x + 1 - x + 6 = 2x + 7

Factor x³ + x² + x + 1 by grouping. What is the resulting expression?

vladimir1956 [14]

<h3>Answer: (x² + 1)(x + 1)</h3>

Work Shown:

x³ + x² + x + 1

(x³ + x²) + (x + 1)

x²(x+1) + 1(x + 1)

(x² + 1)(x + 1)

The basic outline is to pair up the terms into two groups. We factor each group separately, and then factor out the overall GCF (x+1). You can use the FOIL rule to verify the answer.

Multiply (7x – 6)(8x +3). A. 56x 2 – 27x – 18 B. 12x 2 – 50x + 8 C. 56x 2 – 18 D. 56x 2 – 69x + 18

mestny [16]

(7x-6)(8x+3)

Use the FOIL method

F: 7x • 8x = 56x^2
O: 7x • 3 = 21x
I: -6 • 8x = -48x
L: -6 • 3 = -18

$56x^{2}+21x-48x-18$

Simplify
$56x^{2}-27x-18$

Your answer is A.
