Step-by-step explanation:
P(x)= x^2-5x+c=0
P (-2)= (-2)^2-5 (-2)+c=0
= 4+10+c=0
=14+c=0
C=(-14)
Answer:
Step-by-step explanation:
Multiplicative reciprocal of x is 1/x
Eg: Multiplicative reciprocal of 4 is 1/4
Multiplicative reciprocal of 1/8 = 8/1 = 8
Multiplicative reciprocal of 89 is 1/89
When we multiply a number and its Multiplicative reciprocal , the result will be 1
4*1/4 = 1
