Answer:

2x^2 + 3 Answer D

Step-by-step explanation:

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

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

Distribute the "-1"

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

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

3x^2 + 2x + 4 - x^2 -2x -1

Regroup

3x^2 - x^2 + 2x - 2x + 4 - 1

Combine like terms

2x^2 + 0x + 3

2x^2 + 3

Answer:

x ≈ - 6.74, 0.74

Step-by-step explanation:

x² + 6x - 5 = 0 ( add 5 to both sides )

x² + 6x = 5

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 5 + 9

(x + 3)² = 14 ( take square root of both sides )

x + 3 = ± \sqrt{14} ( subtract 3 from both sides )

x = - 3 ± \sqrt{14}

Then

x = - 3 - \sqrt{14} ≈ - 6.74 ( to the nearest hundredth )

x = - 3 + \sqrt{14} ≈ 0.74 ( to the nearest hundredth )
