    Are you trying to simplify?

    Are the variables to a power. Ex. 9y^4.....y^2 ?

    So, you are solving for y?

    So I got 3 real y values. and 4 imaginary.

    these are the answers: 8y2 + 9y3 11y2 11y5 2y2 + 9y3

    I have the answer. Are looking for a simplified version, or for the zeros?

    ~((9y^(4)))+12~(y^(2))-3~(y^(6))-~(4y^(4)) Remove the parentheses. ~(9y^(4))+12~(y^(2))-3~(y^(6))-~(4y^(4)) Pull all perfect square roots out from under the radical. In this case, remove the 3y^(2) because it is a perfect square. 3y^(2)+12~(y^(2))-3~(y^(6))-~(4y^(4)) Pull all perfect square roots out from under the radical. In this case, remove the y because it is a perfect square. 3y^(2)+(12*y)-3~(y^(6))-~(4y^(4)) Multiply 12 by y to get 12y. 3y^(2)+(12y)-3~(y^(6))-~(4y^(4)) Remove the parentheses around the expression 12y. 3y^(2)+12y-3~(y^(6))-~(4y^(4)) Pull all perfect square roots out from under the radical. In this case, remove the y^(3) because it is a perfect square. 3y^(2)+12y+(-3*y^(3))-~(4y^(4)) Multiply -3 by y^(3) to get -3y^(3). 3y^(2)+12y+(-3y^(3))-~(4y^(4)) Remove the parentheses around the expression -3y^(3). 3y^(2)+12y-3y^(3)-~(4y^(4)) Pull all perfect square roots out from under the radical. In this case, remove the 2y^(2) because it is a perfect square. 3y^(2)+12y-3y^(3)-2y^(2) Since 3y^(2) and -2y^(2) are like terms, add -2y^(2) to 3y^(2) to get y^(2). y^(2)+12y-3y^(3) Reorder the polynomial y^(2)+12y-3y^(3) alphabetically from left to right, starting with the highest order term. -3y^(3)+y^(2)+12y
