In case of inequation < or >, draw the line dotted otherwise draw the line thick. This line divides the plane into two equal part..

(2ax) 2 + 2(2ax)b +b 2 = b 2 - 4ac [Adding b 2 to both sides (square of the coefficient of x..

(2ax + b) 2 = b 2 - 4ac [a 2 + 2ab + b 2 = (a+b) 2..

Question 1 - Question: Which of the following equations have x=2, y=3 as solution ? (a) 8x-y = 12 (b) 2x+3y = 10 Answer: (a) Substitute x=2, y=3 in 8x-y=12 8(2)-3=12 16-3=12 x=2, y=3 is not a solution of 8x-y=12 (b) Substitute x=2..
