factor

u^{2} + 8 u + 7

(u + 1) (u + 7)

Solution steps

u^{2} + 8 u + 7

Break the expression into groups

= (u^{2} + u) + (7 u + 7)

Factor out

u

from

u^{2} + u : u (u + 1)

Factor out

7

from

7 u + 7 : 7 (u + 1)

= u (u + 1) + 7 (u + 1)

Factor out common term

u + 1

= (u + 1) (u + 7)

4 x + \frac{1}{4} = 10 x - \frac{x}{2}

3 (x + 1) + 11 < - 2 (x + 13)

21 z^{2} + 85 z - 26 = 0

4 y - (- 2 y - 3) = 9

∣ 7 x + 2 ∣ > 10
