Which can is the polynomial function of the lowest degree with rational real coefficients, a leading coefficient of 3 and roots 5 and 2

y = 3x² - 21x + 30

Step-by-step explanation:

given the polynomial has roots x = 5 , x = 2 , then

(x - 5) and (x - 2) are factors and

y = a(x - 5)(x - 2) ← a is a multiplier

here a = 3

y = 3(x - 5)(x - 2)

  = 3(x² - 7x + 10) = 3x² - 21x + 30

the correct answer is 45x

9×5=45 then add the x

the answer is 45 i just did it on oddesy ware
