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:
68
Step-by-step explanation:
Pythagorean theorem: a²+b²=c² a²=32² b²=60² c²=hypotenuse²
32²+60²=c²
1024+3600= c²
4624=c²
Now, take the square root of both sides of the equation to find c
=c
68=c
