Question

verify whether the following are zeroes of the polynomial indicated against them.
P(x)=(x+1)(x-2) , x=-1, x=2​

Answer 1

Answer:

yes -1 & 2 are zeroes of the given polynomial P(x)

Step-by-step explanation:

given

P(x)=(x+1)(x-2)

P(-1)=(-1+1)(-1-2)=(0)(-3)=0

so -1 is a zero of the given polynomial

P(2)=(2+1)(2-2)=(3)(0)=0

so 2 is zero of the given polynomial

therefore -1 and 2 are zeroes of the given polynomial P(x)=(x+1)(x-2)
