Question

let a be a root, then ( 2 a ) is
also a root.
( 9 a^{3}-27 a^{2}+26 a-8=9left(8 a^{3}right)-27left(4 a^{2}right) )
( 63 a^{3}-81 a^{2}+26 a=0 )
a ( left(63 a^{2}-81 a-26right)=0 )
eifhr ( a=0 ) or
( 63 a^{2}-81 a-26=0 )
( 2 a=frac{84}{126} ) or ( frac{78}{126} )

# *=-2, y = -3, and z = 5 equation Find the zeros of 9x) - 27x2 + 26x - 8, given that double the other * - 27x2 + 26x - 8, given that one of the zeros of this equalis
