3. Show by i) establishing the common factor on the LHS, then ii) dividing each term on the LHS by that common factor and iii) using the exponent laws to make the LHS look like the RHS. a) −7x4y2+14x3y5+21x3y4=7x3y2(−x+2y3+3y2) b) x21+x=x(1+x) c) x25+x21=x(x2+1) d) 2x−23+x−21+x21=xx1(x2+x+2) e) x21y−21+x23y−xy21=yx(1+xyy−yx)
