II) y2 â€“ 6y â€“ 187 = 0

Â

2) I) 3/âˆšx + 7/âˆšx = âˆšx

II) y2 = 125/2/ âˆšy

Â

3) I) 3x = 5y â€“ 4Â Â Â Â Â

Direction (1-5) :

I) x2 â€“ 9x â€“ 252 = 0

(x â€“ 21) (x + 12) = 0

X = 21, -12

II) y2 â€“ 6y â€“ 187 = 0

(y â€“ 17) (y + 11) = 0

Y = 17, -11

Canâ€™t be determined

I) 3/âˆšx + 7/âˆšx = âˆšx

(3 + 7) / âˆšx = âˆšx

X = 10

II) y2 = 125/2/ âˆšy

y2 Ã— âˆšy = 125/2

y2 + (1/2) = 125/2

y5/2 = 125/2

y = 12

x < y

3x – 5y = 4–> (1)

5x + 7y = 70–>(2)

By solving the equation (1) and (2),

X = 7, y = 5

x > y

I) 4x2 + 4x â€“ 48 = 0

4x2 + 16x â€“ 12x â€“ 48 = 0

4x (x + 4) â€“ 12 (x + 4) = 0

(4x â€“ 12) (x + 4) = 0

X = 12/4, -4 = 3, -4

II) 3y2 – 22y + 32 = 0

3y2 – 6y â€“ 16y + 32 = 0

3y (y â€“ 2) â€“ 16 (y â€“ 2) = 0

(3y â€“ 16) (y â€“ 2) = 0

Y = 16/3, 2 = 5.33, 2

Canâ€™t be determined

I) x2 + 24x â€“ 81 = 0

(x + 27) (x â€“ 3) = 0

X = -27, 3

II) y2 + y â€“ 56 = 0

(y + 8) (y â€“ 7) = 0

Y = -8, 7

Canâ€™t be determined
