Question

find the centre and radius of the circle 2x^2+2y^2-3c+2y-1=0​

Answer 1

Answer:

Comparing the given equation with the general form a = 2,h = 3/2, b = -2,g= 3/2, f = 1/2 and c = 1 Condition for two lines to be perpendicular is a + b = 0. Here a + b = 2 – 2 = 0 ⇒ The given equation represents a pair of perpendicular lines.Read more on Sarthaks.com - https://www.sarthaks.com/917810/show-that-2x-2-3xy-2y-2-3x-y-1-0-represents-a-pair-of-perpendicular-lines
