Question

Verify whether x = -2 is a zero of the polynomial 2x² - 40+2​

Answer 1

Answer:

not zero of polynomial

Step-by-step explanation:

If x = 1/2 is a zero of polynomial p(x) = 2x + 1, then p(1/2) should be 0. As p ( 1 2 ) ≠ 0 , Therefore, x = 1/2 is not a zero of the given polynomial.

Answer 2

Answer:

Step-by-step explanation:

we can verify this by simply putting the value of x in the given polynomial and

check whether the remainder is zero or not-----

given - $2x^{2}$ - 40+2   , (x=-2)

putting value :-  2$(-2)^{2}$-38

                       2*4 - 38

                   ==  - 34

Since remainder is not zero  x= -2 is not a zero of given polynomial
