Question

-5 is a zero of p(x)=2x+10

Answer 1

Answer: true -5 is zero of p(x) = 2(x)+10

If you got zero as the ans then it means that x+5 is a factor because x+5=0

x= - 5

and - 5 is a zero of the polynomial

Steps:

P(x) = 2x + 10=0

P(-5) = 2(-5)+10

= - 10+10=0

I hope this is the ans you were looking for!!

Have a great day :-)

Answer 2

yes it is

Step-by-step explanation:

2x+10 = 0

2x= -10

x = -10/2

x =-5

zero of p(x) is -5

for checking

substituting x by -5

p(x)=2x+10

p(-5)=2x(-5)+10

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