Answer 1

Answer:

Step-by-step explanation:

iii). x^2 - 5 = 0

x^2 = 5

x = ± sqr5

ii). x = 1/5 and x = - 1/2

iii). x = (sqr3) / 4 and x = (- 2*sqr3) / 3

The basic relationship between zeros and coefficients in quadratic function

ax^2 + bx +c is

sum of zeros = - (b/a)

product of zeros = c / a
