Question
What will come in place of (?) in the given expression.
(14)² – (12)² = ?Solution
ATQ,
Using identity: a² – b² = (a + b)(a – b)
= (14 + 12)(14 – 12)
= 26 × 2
= 52
I. x² + 3x – 154 = 0
II. y² + 5y – 126 = 0
I. 22x² - 97x + 105 = 0
II. 35y² - 61y + 24 = 0
What are the coordinates of the point which divides the line joining (-1, 7) and (4, 3) in the ratio 2:3?
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 21x² - 122x + 160 = 0
Equation 2: 23y² - 159y + ...
I). p2 + 17p - 234 = 0
II). q2 - 21q + 108 = 0
I. 6x2 + 23x + 10 = 0
II. 2y2 - 3y - 5 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 6x² - 24x + 18 = 0
Equation 2: 5y² - 20y + 15 = 0
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between 'p' and 'q' and choose...
I. x2 – 12x + 32 = 0
II. y2 + y - 20 = 0
I. x2 + 91 = 20x
II. 10y2 - 29y + 21 = 0
