Solve by Completing the Square: x2 + 8x + 6 = 0

Mathematics
1 answer:
BlackZzzverrR [31]4 years ago
4 0

Answer:

X2+8X+6=0

We add all the numbers together, and all the variables

X^2+8X+6=0

a = 1; b = 8; c = +6;

Δ = b2-4ac

Δ = 82-4·1·6

Δ = 40

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

X1=−b−Δ√2aX2=−b+Δ√2a

The end solution:

Δ−−√=40−−√=4∗10−−−−−√=4√∗10−−√=210−−√

X1=−b−Δ√2a=−(8)−210√2∗1=−8−210√2

X2=−b+Δ√2a=−(8)+210√2∗1=−8+210√2

Step-by-step explanation:

In the slope intercept form equation, y =mx+b, m is the slope, or the coefficient of x.
Therefore, the slope, or m, in this situation is -2/3.

For each of the following, select the correct words from the word bank to complete each statement.
Anuta_ua [19.1K]

Answer:

Angles opposite one another that share a vertex are called <u>vertical</u> angles.

When one of these angles undergo a rigid transformation so that it fits exactly over the other, we know that the two angles are <u>congruent</u>

When two parallel lines are crossed by another line called the <u>transversal</u> the angles created inside the parallel lines but on opposite sides of the crossing lines are called <u>alternate</u> <u>interior</u> angles. Angles of this type have the same measurement as one another. Two figures are <u>similar</u> if one can fit exactly over the other after rigid transformations and dilations

Step-by-step explanation:

Vertically opposite angles are always equal (congruent)

The transversal line is the line that crosses two or more parallel lines

Alternate interior angles formed by two parallel lines crossed by a common transversal, are congruent

Two plane geometric figures are similar if they their corresponding interior angles are congruent

How to write in standard form
Lilit [14]
Wen you write in standard form, that means you're writing it in number form. For example, instead of writing "eighty-two", you'll write "82". ;-)
