6x-9w = -3
It can be simplified to: -1-9w
81w2 - p2 = (9w + p) (9w - p)because 81w2 - p2 is the difference of squares. To factor the difference of squares, square root both terms and write the binomial twice:(9w ? p) (9w ? p)Now, to replace the question marks, one binomial has to replace it with the plus sign, while the other binomial gets a minus sign:(9w + p) (9w - p)
9w
-9w + zt + wz - 9t = (z - 9)(t + w)
