Question

Solve by using formula:- x = -b ± √b²-4ac/ 2a y^2-6y+2=0

Answer 1

Answer:

For the nature of the roots we have to find the discriminant of the given equation

D = b²-4ac

= 48-48

D = 0

thus the roots are real and equal

it is the perfect square of √3x - 2

so (√3x-2)²=0

Answer 2

No solution when D = b2 − 4ac < 0 : a2 + 64 > 0 for all real numbers a. So for every real a the equation has a solution. 11 (4). { x + 3y = 5. 2x + y ...
