factor-k^2+4+(-k)

factor

- k^{2} + 4 + (- k)

- (k - \frac{- 1 + 17}{2}) (k - \frac{- 1 - 17}{2})

Solution steps

- k^{2} + 4 + (- k)

Remove parentheses:

(- a) = - a

= - k^{2} + 4 - k

Factor out common term

- 1

= - (k^{2} + k - 4)

Factor

k^{2} + k - 4 : (k - \frac{- 1 + 17}{2}) (k - \frac{- 1 - 17}{2})

= - (k - \frac{- 1 + 17}{2}) (k - \frac{- 1 - 17}{2})

5 a 2 + b

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

4 n^{2} - 7 x^{2} y + 4 n y - 7 n x^{2}

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

4 a d - 4 ab - c d + b c
