Answer:
Correct option is:
A. -1 and 10
Step-by-step explanation:
If a,b are the roots of Ax²+Bx+C=0
then, a+b= -B/A
The polynomial (x+ p)(x+q) has roots -p and -q
x²+ 9x +10= (x+ p)(x+q)
i.e. -p and -q are roots of x²+ 9x +10
Hence, -p-q= -9
i.e. p+q=9
Hence, The correct value of pa and q are:
p= -1 and q= 10
i.e. Correct option is:
A. -1 and 10
