Question

verify whether the following are zeros of the polynomial indicated against them.
1)p(x)=(x+1)(x-2) ,x= -1,2
2)p(x)=lx+m, x=-m/l​

Answer 1

Answer:

1) 0

2)0

Step-by-step explanation:

1) Put x = - 1

=>p(x) = (x + 1) (x – 2)

=>p(-1) = (-1 + 1) (-1 – 2)

=>p(-1) = (0) (-3)

=>p(-1) = 0

Now put x = 2 we get

Put x = 2

=>p(x) = (x + 1) (x – 2)

=>p(2) = (2 + 1) (2 – 2)

=>p(2) = (3) (0)

=>p(2) = 0

2) Put x  = - m/l we get

=> p(x) = lx + m

=> p(-m/l) = l(-m/l) + m

=> p(-m/l) = -m + m

=> p(-m/l) = 0

Answer 2

Answer:

once I was also was gone mad ,when someone asked me that question.

after I got that answer was false
