simplify a/b+b/a+2

Solution

simplify

\frac{a}{b} + \frac{b}{a} + 2

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

Solution steps

\frac{a}{b} + \frac{b}{a} + 2

Join

\frac{a}{b} + \frac{b}{a} : \frac{a ^{2} + b ^{2}}{ab}

= \frac{a ^{2} + b ^{2}}{ab} + 2

Apply the fraction rule:

a + \frac{b}{c} = \frac{a c + b}{c}

= \frac{2 ab + a ^{2} + b ^{2}}{ab}

\frac{1 0 ^{5} + 1 0 ^{4} + 1 0 ^{3} - 5 x 1 0 ^{4}}{104}

(4 x - 8)^{3}

y + 5 (x^{8}) - 21

(\frac{7 x}{3 y})^{2}

[3 (2 x - 3 y)]^{2} + [4 (2 x + 3 y)]^{2}
