Answer:
8x2-30x+27 has one root (9/4) the square of the other (3/2)
Step-by-step explanation:
8x2+30x+27 = (2*x+3)*(4*x+9) => solution = {-3/2, -4/9}
One is not the square of the other because squares are positive.
8x2-30x+27 = (2*x-3)*(4*x-9) =>
solution = {3/2, 4/9} since (4/9 = (3/2)^2, therefore the preceding question is correct.
