1} It is actually easy and there are two methods for you . You can either derive the roots of the polynomial by middle split method or here is the other one.

(Let alpha be p and beta be q for both questions because i dont have thes symbols in my keyboard)

=>4x²+3x+7

p+q=-3/4}. Relationship between

pq=7/4. }. Zeroes and coefficient

Now, 1/p+1/q=p+q/pq. (Lcm)

=>-3/4 ÷7/4

-3/4×7/4

=-3/7. (ans.)

2} Here, it is given that:

p and q are the zeroes and

q=1/p

Now, pq=c/a

=>p×1/p=4k/k²+4

4k/k²+4=1

k²+4=4k

K²-4k+4=0

K²-2(2)(k)+2²=0

(K-2)²=0

=>K=2. (ans.)
