we know we can write this as one plus sign. Age of Axe over co sign H of X, divided by one minus Sign H of X over co sign H of acts. This simplifies to co sign a chav axe was signed H of X over co sign a check box minus signed H of X, which is equivalent to either the axe over eat of the negative axe, which is either the two packs because it&#x27;s maximize negative X, which is expose sex, which is two X. Okay, now we can write this out. A sign a chair backs is eating the axe months. Each of the negative X over to and coast John H. Of X is either the axe plus E to the negative axe over, too. Therefore, tangent H of Axe, the Sign Age Max over co sign a check box.
