(8m^2-24m-3+3√17)/4 * (8m^2-24m-3-3√17)/4
4m⁴-24m³+33m²+9m-9=0
re-write the polynomial equation as:
4m⁴-24m³+36m²-3m²+9m-9=0
because: 36m²-3m²=33m²
re-grouping
(4m⁴-24m³+36m²)-(3m²-9m)-9
factor out 4
4(m⁴-6m³+9m²)-(3m²-9m)-9
note:
m⁴-6m³+9m²=(m²-3m)²
therefore,we ve:
4(m²-3m)²-(3m²-9m)-9=0
4(m²-3m)-3(m²-3m)-9=0
so,another form of rewriting 4m⁴-24m³+33m²+9m-9=0, is
4(m²-3m)²-3(m²-3m)-9=0
let
(m²-3m)=a
therefore,we ve:
4a²-3a-9=0
solve for a.
recall:
solving the two equation quadratically will give the root of the polynomial
then u no what to do agn
i think steve is right
