Answer:1
Step-by-step explanation: solving for d
Since units are same, they can be disregareded for now
12 to 10=12:10
treat as fraction
12/10=6/5
ratio is 6:5
If the roots are 1 and 3, the factors of this quadratic are (x-1) and (x-3).
The polynomial is x^2 - 4x + 3.
If you were supposed to write a polynomial based upon all four given roots, then:
Looks as tho' you have four distinct roots. The 4th order polynomial with these roots is f(x) = (x-1)(x-3)(x-7)(x-2). Multiply this out, combine like terms and then arrange the terms in descending order by powers of x.
