Answer:
( 2x + 1 ) (x + 1 )
Step-by-step explanation:
2x² + 7x + 3
m+n = b = <u>7</u>
m · n = a · c = 2 · 3 = <u>6</u>
m = 6
n = 1 because 6 + 1 = <u>7</u> and 6 · 1 = <u>6</u>
2x² + <u>1</u>x + <u>6</u>x + 3
x ( 2x + 1 ) + 3 ( x + 1 )
( 2x + 1 ) (x + 1 )

<span>Two problems such as 150,000 + 150,000 = 300,001 and 500,000 - 200,000 = 300,000 could show that two problems can give the same result. A third could be 400,000 - 148,000 = 252,000 but rounds to 300,000 when rounded. All three give the same result when rounded to the nearest hundred thousand.</span>
