expand (2+sqrt(3))^2-(2-sqrt(3))^2

expand

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

83

Decimal Notation

13.85640 \dots

Solution steps

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

Expand

(2 + 3)^{2} : 7 + 43

= 7 + 43 - (2 - 3)^{2}

Expand

- (2 - 3)^{2} : - 7 + 43

= 7 + 43 - 7 + 43

7 + 43 - 7 + 43 = 83

= 83

\frac{x + 2}{x ( x + 4 )}

\frac{( 2 x + 1 ) ^{2}}{x ( - 1 + x )}

\frac{9 x ^{2} - 4 x + 5}{( 3 x + 1 ) ( 3 x - 1 ) ( 2 x - 3 )}

\frac{( x + y - 1 ) ^{2}}{4 x ^{2}}

3 x^{2} (x^{2} + sin (4 x))
