simplify ((a^2-b^2))/(a+b)-(a+b)^2+2(a^2+ab)

simplify

\frac{( a ^{2} - b ^{2} )}{a + b} - (a + b)^{2} + 2 (a^{2} + ab)

a^{2} + a - b^{2} - b

Solution steps

\frac{a ^{2} - b ^{2}}{a + b} - (a + b)^{2} + 2 (a^{2} + ab)

Cancel

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

= a - b - (a + b)^{2} + 2 (a^{2} + ab)

Expand

- (a + b)^{2} : - a^{2} - 2 ab - b^{2}

= a - b - a^{2} - 2 ab - b^{2} + 2 (a^{2} + ab)

Expand

2 (a^{2} + ab) : 2 a^{2} + 2 ab

= a - b - a^{2} - 2 ab - b^{2} + 2 a^{2} + 2 ab

Group like terms

= - a^{2} + 2 a^{2} + a - b^{2} - b - 2 ab + 2 ab

Add similar elements:

- a^{2} + 2 a^{2} = a^{2}

= a^{2} + a - b^{2} - b - 2 ab + 2 ab

Add similar elements:

- 2 ab + 2 ab = 0

= a^{2} + a - b^{2} - b

(5^{2})^{- 3}

(\frac{81}{16})^{- \frac{3}{4}}

- 8 x - 10 = 38

0.0000089 = x ((0.042) (0.042))
