expand (k+1)!*(k+2)-1

expand

(k + 1)! \cdot (k + 2) - 1

k (k + 1)! + 2 (k + 1)! - 1

Solution steps

(k + 1)! (k + 2) - 1

Expand

(k + 1)! (k + 2) : k (k + 1)! + 2 (k + 1)!

= k (k + 1)! + 2 (k + 1)! - 1

\frac{2 - x - 3}{( x + 7 ) ( x - 7 )}

\frac{lo g _{10} ( x )}{( lo g _{10} ( x ) + 1 ) ^{2}}

\frac{x ^{3} - 8 x ^{2} - 1}{( x + 3 ) ( x - 2 ) ( x ^{2} + 1 )}

(e^{- x} - x)^{2}

(1 + y^{2}) d x + (x^{2} y + y) d y
