Question

1. Find the zeroes of the following and verify the relationship with the coefficients: - ii. x ^ 2 - 225​

Answer 1

Answer:

Zeroes are 15 and -15.

Step-by-step explanation:

x^2 - 225 = 0

x^2 - 15^2 = 0

(x + 15) (x - 15) = 0

x = -15 & 15

x^2 - 225 = x^2 + 0 × x - 225

-15 + 15 = 0 = -0/1 = -b/c

-15 × 15 = -225 = c/a
