The correct answer is D
1.3wx = 40 – wy
2. b2 = 2b + p
3. d2 + d = q
Now, observe the given conditions:
One root of equation...
I. 66x² - 49x + 9 = 0
II. 46y² - 37y - 30 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 24x + 143 = 0
Equation 2: y² - 26y + 165 = 0
I. 4x2 + 9x - 9 = 0
II. 4y2 - 19y + 12 = 0
I. x² - 19x + 84 = 0
II. y² - 25y + 156 = 0
I. y² + y – 56 = 0
II. 2x² + 11 x – 40 = 0
If a and b are the roots of x² + x – 2 = 0, then the quadratic equation in x whose roots are 1/a + 1/b and ab is
I. 5x2 – 18x + 16 = 0
II. 3y2 – 35y - 52 = 0
I. 2x2 + 13x + 21 = 0
II. 3y2 + 34y + 63 = 0
I. 2p2 + 25p – 13 = 0
II. 2q2 – 19q = 2q + 23
