Write the quadratic equation whose roots are 6 and 5, and whose leading coefficient is 3

y = 3x^2 - 33x + 90

Step-by-step explanation:

y= 3(x - 6)(x - 5)

if you expand this you get

y = 3(x^2 - 6x - 5x +30)

y = 3(x^2 - 11x + 30) Now use the 3

y = 3x^2 - 33x + 90

And that would be the answer.
