lol....well the method I would use is to multiply each term on the right by the x term on the left and then multiply each term on the right with the -3 term on the left. 1st part produces x^4-4x^3+2x^2-7x 2nd part gives -3x^3+12x^2-6x=21 adding like terms from 1st and 2nd parts we get x^4-7x^3+14x^2-13x=21...hope that helps!!!!!
