Answer: 5x^2 + 3x + 1

Step-by-step explanation:

1.) Put the two equations together into an addition problem.

<em>3x^2 + 4x + 2x^2 - x + 1</em>

2.) Combine like terms.

<em>3x^2 + 2x^2 = 5x^2</em>

<em>4x - x = 3x</em>

<em>1 = 1</em>

3.) Order the like terms together.

<em>5x^2 + 3x + 1</em>

Solve algebraically: x2 − x ≥ 6.
hammer [34]

Answer:

B. x ≥ 3 or x ≤ −2

Step-by-step explanation:

<u>Inequalities</u>

Solve the inequality:

x^2-x\ge 6

Subtracting 6:

x^2-x-6\ge 0

Factoring:

(x-3)(x+2) ≥ 0

We have a product that must be greater or equal to 0. This can only happen if:

x - 3 ≥ 0  and x + 2 ≥ 0

Or:

x - 3 ≤ 0  and  x + 2 ≤ 0

The first couple of conditions yields to:

x ≥ 3 and x ≥ -2

Which lead to the solution

x ≥ 3       [1]

The second couple of conditions yields to:

x ≤ 3 and x ≤ -2

Which lead to the solution

x ≤ -2        [2]

The final solution is [1] or [2]:

Answer:

B. x ≥ 3 or x ≤ −2
