Question

verify that -3 and 5 are the zero of the polynomial q(x)=(x+3) (x-5)​

Answer 1

Answer:

put eq = 0

Step-by-step explanation:

q(x) = 0

(x+3)(x-5)=0

x+3 = 0/(x-5)

x+3 = 0

x= -3

Thus, it is a zero of the polynomial

Also,

x-5=0/(x+3)

x-5 = 0

x = 5

Hence, it is a zero of the polynomial
