Question

if 5 is the zero of the polynomial p(x) =x2-(p-1) x+10 find the value of'p'
​

Answer 1

Answer:

p= 8

Step-by-step explanation:

Answer 2

Answer:

p = 8

Step-by-step explanation:

put 5 instead of x in the equation you'll get that

x² -(p-1)x +10 = 0

5² -(p-1)5 + 10 = 0

25 -(p-1)5 +10 =0

-(p-1)5 = -35

p-1 = 35/5

p = 7+1 =8
