Question

find the roots of quadratic equation ​

Answer 1

Answer:

Step-by-step explanation:

3x²=15x

Put x=0

We get one root

other root

3x²=15x

3x=15

x=5

Answer 2

Answer:

(5,0)

Step-by-step explanation:

3x²-15x+0=0 (given)

Now in this equation,

a=3

b= -5

c=0

Now,

=-b±√b²-4ac/2a

=-(-15)±√(-15)²-4(3)(0)/2(3)

=15±√225/6

=15±15/6

Case-1                                        Case-2

15+15/6                                        15-15/6  

=30/6                                           =0/6

=5                                                 =0
