expand sqrt(3(x+h)^2-1)-sqrt(3x^2-1)

expand

3 (x + h)^{2} - 1 - 3 x^{2} - 1

3 x^{2} + 6 x h + 3 h^{2} - 1 - 3 x^{2} - 1

Solution steps

3 (x + h)^{2} - 1 - 3 x^{2} - 1

3 (x + h)^{2} - 1 = 3 x^{2} + 6 x h + 3 h^{2} - 1

= 3 x^{2} + 6 x h + 3 h^{2} - 1 - 3 x^{2} - 1

\frac{36 x}{( x ^{2} + 9 ) ^{2}}

cos (x) (1 - sin (x))

\frac{1 - 2 e ^{- s}}{s ^{2} ( s ^{2} + 1 )}

\frac{( x + 2 ) ^{3}}{3}

1 + cos (x) (1 + cos (x))
