Question

. If pq = -56 and p+q = -1, then the value of p and q are​

Answer 1

Answer:

P=-8or7

Q=7or-8

Step-by-step explanation:

P+Q=-1

PQ=-56

P=-56/q put in equation 1

(-56/q)+q=-1

(-56+q^2)/q=-1

(-56+q^2)=-q

q^2+q-56=0

(q-7)(q+8)=0

Q=7,-8

When q=7

P+7=-1

P=-8

When q=-8

P+(-8)=-1

P-8=-1

P=8-1

P=7

Answer 2

Answer:

p= -8

q=7
