simplify 3y(y+sqrt(2))(y-sqrt(2))+5

simplify

3 y (y + 2) (y - 2) + 5

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

Solution steps

3 y (y + 2) (y - 2) + 5

Apply Difference of Two Squares Formula:

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

(y + 2) (y - 2) = y^{2} - (2)^{2}

= 3 y (y^{2} - (2)^{2}) + 5

Simplify

y^{2} - (2)^{2} : y^{2} - 2

= 3 y (y^{2} - 2) + 5

\frac{( e ^{- 5 s} + s ^{2} + s )}{s ( s ^{2} + 4 )}

\frac{1}{1000} x^{3} - 76 x^{2} + 1228 x - 2160

(- 2 x + 23)^{2}
