Answer:
Y= - 3/x+2/3
Step-by-step explanation:
When a quadratic equation ax^2+bx+c has a double root, the discriminant,
D=b^2-4ac=0
Here
a=2,
b=b,
c=18
and
D=b^2-4ac=b^2-4*2*18=0
solve for b
b^2-144=0
=> b= ± sqrt(144)= ± 12
So in order that the given equation has double roots, the possible values of b are ± 12.
To do multiplication, what you must do is multiply each number from right to left and add.
For example
60 * 4
4 * 0 = 0
6 * 4 = 24
The result is
240
answer
60 * 4 = 240
