I could be wrong, but I'm going to go with equal to.
Multiply the coefficient of the first term by the constant 1 • -31 = -31
Find two factors of -31 whose sum equals the coefficient of the middle term, which is -2 .
-31 + 1 = -30
-1 + 31 = 30
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
<h3>Given :</h3>
- Distance = 175
- Time 1 = 4 hours

<h3>To find:</h3>
- Different between two speeds when distance is same.

<h3>Solution:</h3>
<u>Part</u><u> </u><u>1</u><u> </u><u>:</u>
In first part we will find speed 1 in which time is 4 hours
we know:-

So:-





<u>Part 2</u>
In first part we will find speed 2 in which time is 3 hours
Again:








<u>Part 3</u>
In this part we will find different between speed 1 and speed 2


So :







Your answer will be 191.66
