Equation: x² + 10x + 21
<u>Step</u><u> </u><u>1</u><u>:</u> Find two numbers that can add up to 10 and be multiplied to 21. We have: 7 & 3, in the sense that 7+3=10, and 7×3=21. Replacing 10 with 7+3, the equation is now → x² + 7x + 3x + 21
<u>Step</u><u> </u><u>2</u><u>:</u> Get the new equation bracketed → (x² + 7x) (+3x + 21)
<u>Step</u><u> </u><u>3</u><u>:</u> Use 'x' in the equation. For the first part, we have 'x'. x² = x × x so, bring out one x out side the bracket, divide 7x by = 7 → x (x +7). Do the same for the second part by dividing 21 by 3 = 7, and then bringing out 3 from the bracket → 3 (x + 7).
Bringing everything together, we have: x(x+7) +3(x+7) → (x+3) (x+7)

Answer:
<h2>3x + 6y = 0</h2>
Step-by-step explanation:
Equation of a line = y = mx + c
where m = slope
m = (1 - 4) / (-2 - (-8))
<h3>m = -3 / 6</h3>
y - 1 = -3/6 (x + 2)
6y - 6 = -3x - 6
3x + 6y = 0
Based from background knowledge, I believe that the correct answer among all of the given choices would be B.) 38/2. This would give you 19. If I am mistaken, please correct me. But I am definitely positive that this is the right answer.
I hope this is the answer you were looking for and that it helps!! :)
