Solve a/(a-b)^2-0/(b-a)^2

$$\frac { a } { ( a - b ) ^ { 2 } } - \frac { 0 } { ( b - a ) ^ { 2 } }$$

Evaluate

$$\frac{a}{\left(a-b\right)^{2}}$$

Short Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Expand \left(b-a\right)^{2}.

$$\frac{a}{\left(a-b\right)^{2}}-\frac{0}{\left(a-b\right)^{2}}$$

Since \frac{a}{\left(a-b\right)^{2}} and \frac{0}{\left(a-b\right)^{2}} have the same denominator, subtract them by subtracting their numerators.

$$\frac{a-0}{\left(a-b\right)^{2}}$$

Do the multiplications in a-0.

$$\frac{a}{\left(a-b\right)^{2}}$$

Expand \left(a-b\right)^{2}.

$$\frac{a}{a^{2}-2ab+b^{2}}$$

$$\frac{a}{\left(b-a\right)^{2}}$$
