R.H. Whittaker proposed the five-kingdom classification in 1969. This classification was based upon certain characters like mode of nutrition, thallus organization, cell structure, phylogenetic relationships and reproduction.
I. 63x2+ 148x + 77 = 0
II. 21y2+ 89y + 88 = 0
I. x2 – 36 = 0
II. y2 - 7y + 6 = 0
I. 4x² - 15x + 9 = 0
II. 20y² - 23y + 6 = 0
I. x2 + x – 42 = 0
II. y2 + 6y – 27 = 0
I. 49y2+ 35y + 6 = 0
II. 12x2+ 17 x + 6 = 0
I. 3x2 + 3x - 60 = 0
II. 2y2 - 7y + 5 = 0
I. 35x² + 83x + 36 = 0
II. 42y² + 53y + 15 = 0
I. x2 – 10x + 21 = 0
II. y2 + 11y + 28 = 0
I: 3x² - 18x + 24 = 0
II: 5y² + 10y - 15 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 37x² - 172x + 135 = 0
Equation 2: 29y² - 132y +...
