Question

Verify whether the following are zeros of the polynomials indicated against them. write also the value P (x) = 5x² -3x + 7 at x= 2​

Answer 1

Answer:

P(x) = 5x²-3x+7

Substituting 2 at place of x,

P(2) = 5(2)² - 3(2) + 7 = 5(4) - 6 + 7 = 20 - 6 + 7 = 21

21 is not equal to 0.

Hence, x = 2 is not the zero of the polynomial.

Answer 2

Maybe there is some mistake in the the value of X

but i have still solved it.
