Pls help me so i can pass this question

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

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

Which linear inequality is represented by the graph?
