I. ` x^(2) + 28x + 192 = 0`
II. ` y^(2)+16y+48=0`

I. 5x^(2) + 28x + 15 = 0 II. 6y^(2) + 35y + 25 = 0

I. 4x^(2) - 48x + 143 = 0 II. 4y^(2) - 52y+165 = 0

I. 12x^(2) + 82 x + 140 = 0 II. 16y^(2) + 48y+ 32 = 0

I. x^(2) + 4x+4 = 0 II. y^(2) - 8y + 16 = 0

2x^(2) - 15x + 28 = 0 4y^(2) - 23y+30 = 0

x^(2) - 10x+24 = 0, y^(2) - 14y+48 = 0

In each of the following questions, two equations are given. You have to solve them and I. x^(2)+23x+42=0 II. y^(2)+16y+28=0

(i) 7x^(2) + 16x - 15 = 0 (ii) 5y^(2)+ 8y - 21 = 0
