Question

the zeros of the polynomial are -1,3 ,what will be the expression of the polynomial ​

Answer 1

Answer:

The zero of the polynomial is defined as any real value of x, for which the value of the polynomial becomes zero.

if x=−3x=−3 then

In the equation x2−2x−15x2−2x−15

⇒(−3)2−2×−3−15⇒(−3)2−2×−3−15

⇒9+6−15=0⇒9+6−15=0

if x=5x=5 then

In the equation x2−2x−15x2−2x−15

⇒(5)2−2×5−15⇒(5)2−2×5−15

⇒25−10−15=0⇒25−10−15=0

Hope it's help you

Answer 2

Answer:

The zero of the polynomial is defined as any real value of x, for which the value of the polynomial becomes zero.

if  x= − 3  then In the equation  

x 2 − 2 x − 15 ⇒ ( − 3 ) 2 − 2 × − 3 − 15

⇒ 9 + 6 − 15 = 0

if  x = 5  then In the equation  

x 2 − 2 x− 15 ⇒ ( 5 ) 2 − 2 × 5 − 15

⇒ 25 − 10 − 15 = 0
