Question
For a =-4 and b = 5, value of a² – b²
is:Solution
a = -4, b = 5 a² – b² =(a+b) (a-b) = (-4+5) (-4-5) =-9.
I. p²= ∛1331
II. 2q² - 21q + 55 = 0
I. 6p2 – 7p = 5p – 7p2 + 25
II. 11q2 – 63q + 90 = 0
I. 96y² - 76y – 77 = 0
II. 6x² - 19x + 15 = 0
I. 8x² + 2x – 3 = 0
II. 6y² + 11y + 4 = 0
I. √(17x) + √51 = 0
II. √(4y) + 3 = 0
I. x² - 19x + 84 = 0
II. y² - 25y + 156 = 0
1.3wx = 40 – wy
2. b2 = 2b + p
3. d2 + d = q
Now, observe the given conditions:
One root of equation...
I. 2y² - 35y + 132 = 0
II. 2x² - 31x + 110 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 37x² - 172x + 135 = 0
Equation 2: 29y² - 132y + ...
I. x= √(20+ √(20+ √(20+ √(20…………….∞)) ) )
II. y= √(5√(5√(5√(5……….∞)) ) )
