>What are the factors of 2x\(^2\) - xy - 3y\(^2\) ?
(2x + 3y)(x + y)2
(2x + 3y)(x + y)
(2x + 3y)(x - y)
(2x - 3y)(x + y)
(2x - 3y)(x - y)
Correct answer is D
2x\(^2\) - xy - 3y\(^2\)
= 2x\(^2\) + 2xy - 3xy - 3y\(^2\)
= 2x(x + y) - 3y(x + y)
= (2x - 3y)(x + y)
A quadratic equation with roots -1\(\frac{1}{2}\) and \(\frac{1}{4}\) is
x2 + 3x + 4 = 0
8x2 + 10x + 3 = 0
8x2 +12x – 3 = 0
8x2 + 10x-3.= 0
8x2 + 12x + 3 = 0
Correct answer is D

Correct answer is D
Area of a square = L X L = 81
: L = 9
Perimeter of square = 4 X L
4 X 9 = 36cm
An equilateral triangle with equal sides:
36/3 = 12cm
