Solution
Epiricania melanoleuca parasitizes Pyrilla perpusilla on sugar cane, and is an adult parasitoid belonging to the order Lepidoptera
I. 2x2 - 15x + 25 = 0
II. 3y2 - 10y + 8 = 0
I. 17x² - 26x – 16 = 0
II. 17y²- 26y + 9 = 0
I). p2 + 22p + 72 = 0,
II). q2 - 24q + 128 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 32x + 207 = 0
Equation 2: y² - 51y + 648 = 0
I. 66x² - 49x + 9 = 0
II. 46y² - 37y - 30 = 0
I. y² - 7 y – 18 = 0
II. x² + 10 x + 16 = 0
I. 2x² - 9x + 10 = 0
II. 3y² + 11y + 6 = 0
I. 27x² + 120x + 77 = 0
II. 56y² + 117y + 36 = 0
I). p2 = 81
II). q2 - 9q + 14 = 0
The equation q2 - 17x + C = 0, has two roots ‘x’ and ‘y’ such that (x – y) = 7. Find an equation which is equal to thrice of the gi...
