Answer:
The quadratic equation for the given roots 6 , is y = 3 x² - 20 x + 12
Step-by-step explanation:
Given as :
The roots of the quadratic equation are 6 ,
Let The standard quadratic equation
a x² + b x + c = 0
So, the roots are = 6
And =
Sum of roots =
i.e = 6 +
=
<u>The quadratic equation</u>
y = (x - α) (x - β)
Or, y = (x - 6) (x - )
Or, y = x² - x - 6 x + (6 ×
)
Or, y = x² - ( + 6) x + 4
Or, y = x² - ( ) x + 4
Or, y = x² - x + 4
Or, y = 3 x² - 20 x + 12
Hence, The quadratic equation for the given roots 6 , is y = 3 x² - 20 x + 12 . Answer
