​

Answer 1

QUESTION -

Find the zero of the polynomial

p(x) = 2x + 5

ANSWER -

p(x)=2x+5

2x+5=0

2x=0-5

2x= -5

x= -5/2

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

p(-5/2)= 0

therefore,

p(x)= 0.so, x is the zero of the polynomial= 2x+5

Answer 2

Answer:

for finding zero of any polynomial, we equate the polynomial with zero

so, 2*+5=0

2*=-5

*=-5/2

so -5/2isthe zero of the given polynomial
