Question

Find the zeros of the polynomial x2-7​please answer step by step

Answer 1

Answer:

x = ± $\sqrt{7}$

Step-by-step 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 = ± $\sqrt{7}$

Thus the exact solutions are

x = - $\sqrt{7}$ , x = $\sqrt{7}$
