The addition and subtraction of rational expression is done in the same manner as we do for fractions. This means that for adding and subtracting rational expressions depends whether they have same or different denominators. But an important point to be noted here is that you can add or subtrac...
Therefore, the difference between2xand–7xis9x. Solution (Vertical Method) Algebraic Expression Subtraction ProcessStep-by-step Explanation 2x ––7x ———–Set up the addition vertically. 2x + 7x ———–Distribute the minus sign to the term in the subtrahend. Thus, the–7xwill become7x. T...
