Substitute the values of p and y into the expression -p2 + 2pq -3p2 - 3q2 + pq - q2. Match that value to one of the numbers. 1. p = √3, q = √27
2. p = 2√2, q = -√8
3. p = 0.5, q = 1.5
4. p = -1, q = 2
5. p = 1/4, q = - 2/5
6. p = 1.5, q = –0.5
7. p = -2, q = -2
8. p = 2/5, q = 1/4

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
