Question

If p=1,q= -1, then the value of p cube - q square +2pq - 2p - m is - 4. Find the value of m​

Answer 1

Answer:

m=1

Step-by-step explanation:

p^3 = 1

q^2 = 1

2pq = -2

2p =2

then, p cube -q square +2pq - 2p - m = 4

substituting the values

1 -1 - 2 - 1 -m = -4

-3 - m = -4

- m = -4+3

m = 1
