What ratios can be equivalent to 1 and 8

Find the roots of the equation below. x^2 - 6 + 9 = 0

Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
