expand-sqrt(2)(2-sqrt(5))

expand

- 2 (2 - 5)

- 22 + 10

Decimal Notation

0.33385 \dots

Solution steps

- 2 (2 - 5)

Apply the distributive law:

a (b - c) = ab - a c

- 2 (2 - 5) = - 2 \cdot 2 - (- 2) 5

= - 2 \cdot 2 - (- 2) 5

- 2 \cdot 2 - (- 2) 5 = - 22 + 10

= - 22 + 10

(2 q + \frac{1000}{q ^{2}}) \cdot q

(e^{2 x} + 1) (e^{x} + 1)

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

- \frac{2 a ( b ^{2} - 3 x ^{2} )}{( x ^{2} + b ^{2} ) ^{3}}

(x 3 - y)^{2}
