Question

Find the zeros of the polynomial x2-7​

please answer step by step

Answer 1

x = ±
`√(7)`

Explanation:

To find the zeros equate the polynomial to zero, that is

x² - 7 = 0 ( add 7 to both sides )

x² = 7 ( take the square root of both sides )

x = ±
`√(7)`

Thus the exact solutions are

x = -
`√(7)` , x =
`√(7)`
