(x+2)(5-y)=5x-2y-xy+10 ----i forgot how it is supposed to be arranged.. i only remembered how to arrange answers to those who are raised to a power. 2(5x+5)=10x+10=10(x+1)(3x+4+3d)(2x+3)you have to multiply first 2x to (3x+4+3d) 6x raised to 2 + 8x + 6xdthen multiply 3 to (3x+4+3d) 9x+12+9dthen add those which are like terms= 6x raised to 2+17x+6xd+9d+12(4x+5)raised to 3 same formula as above...there is a shortcut for these type of problems but in case u need a solution, it's just the same as above but a little longer. =64x raised to 3+ 235x raised to 2 + 300x+ 125i could not answer the last one... i forgot how to divide polynomials...
