factor

r^{2} - 2 r - 35

(r + 5) (r - 7)

Solution steps

r^{2} - 2 r - 35

Break the expression into groups

= (r^{2} + 5 r) + (- 7 r - 35)

Factor out

r

from

r^{2} + 5 r : r (r + 5)

Factor out

- 7

from

- 7 r - 35 : - 7 (r + 5)

= r (r + 5) - 7 (r + 5)

r + 5

= (r + 5) (r - 7)

4 u^{2} + 28 u + 49

2 (h + 2) + 7 = - 3

0.04 m^{2} - n^{2}

(\frac{2}{9})^{- 1}

6 t (t + 4) = t - 20
