The answer=>
For this,we need to know what's Middle splitting method
- In order to factorize x² + bx + c we have to find numbers p and q such that p + q = b and pq = c. After finding p and q, we split the middle term in the quadratic as <em><u>px + qx and</u></em> get desired factors by grouping the terms.
Step-by-step explanation:
i.e
Alpha= Beta = 4
5x^3 -3x^2 +8x +10 Just combine all the like terms and multiply everything in the second parentheses by -1
Let the speed of the current be x mi/hr
speed upstream=(12-x) mi/hr
speed downstream=(12+x) mi/hr
It takes 3 hours longer to travel upstream than downstream, thus
time taken upstream=68/(12-x)
time taken to travel downstream=68/(12+x)
the difference in time will be:
68/(12-x)-68/(12+x)=3
solving for x we get:
x=2.98 mi/hr
Thus the rate of current is 2.98 mi/hr

4x+17+x+23+80=180. Now combine like terms.
5x+120=180
5x=60
X=12
