Question

find the number of zeros of the given polynomial and also find their values q(y)=y^2-1​

Answer 1

Answer:

The values of zeros are -1 and 1.

Step-by-step explanation:

y² - 1 = 0

y² - 1² = 0

Use formula: a² - b² = (a + b)(a - b)

(y + 1)(y - 1) = 0

y + 1 = 0     ;  y - 1 =0

y = -1          ; y = 1
