expand ,(1/((x+3)^2)-4)

expand

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

\frac{1}{x ^{2} + 6 x + 9} - 4

Solution steps

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

(x + 3)^{2} = x^{2} + 6 x + 9

= \frac{1}{x ^{2} + 6 x + 9} - 4

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

(f (x) = 2, x^{4} - 3 x^{2} + 5 x - 6) - (g (x) = 2 x^{2} - 7 x + 10)

(m E + m (E - U))^{2}

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

sin (2 x) (cos (5 x) cos (3 x) - sin (3 x) sin (x))
