Answer: 
Step-by-step explanation:
Given: u and v be are the solutions of 
Let 
is the quadratic equation and u and v are the zeroes/solutions then
Sum of zeroes; 
Product of zeroes; 
Comparing to
we get a= 3 , b= 5 and c = 7
Now we have to find
adding and subtracting 2uv in numerator we get
Substituting the values from (i) and (ii) we get
Hence, the value of 
is
Answer:
<h3>x = 1/8</h3>
Step-by-step explanation:
1/7(x+3/4) = 1/8
Multiply 1/7 with x and 3/4
1/7x + 3/28 = 1/8
Multiply everything by 7, so x is a whole number
x + 21/28 = 7/8
Convert 21/28 into a similar like denominator to 7/8
x + 6/8 = 7/8
x = 7/8 -6/8
x = 1/8

-32/1. Is the answer you just divide too and bottom by the bottom number which 3 is an common factor in both #,s
50 + 3x = 7x + 12
This is because of the exterior angle theorem.
