Please help with this circuits problem!! Cannot figure it out!

What are the values of the coefficients A and B in this expression?

Determine the numerical values of the D, E, and F coefficients.

Solve the quadratic equation obtained in Part 5 for the two values of reactance X_C which accomplish the resonance condition.

Now obtain the two capacitance values C₁ and C₂ which would accomplish the resonance condition.

Determine the value of Cin the network shown in the figure for the circuit to be in resonance. 3 (2 Vo(t) 4 cos 7 t V t 2 (2 5 H

equal admitance R+jXc

Y=(R-jXc)/(R²+Xc²)

R=2,

A=2

B=4
