factor x^2+16x+63

factor

x^{2} + 16 x + 63

(x + 7) (x + 9)

Solution steps

x^{2} + 16 x + 63

Break the expression into groups

= (x^{2} + 7 x) + (9 x + 63)

Factor out

x

from

x^{2} + 7 x : x (x + 7)

Factor out

9

from

9 x + 63 : 9 (x + 7)

= x (x + 7) + 9 (x + 7)

Factor out common term

x + 7

= (x + 7) (x + 9)

∣ 10 - x ∣ > 5

8 x = 16

\frac{1}{2 π \cdot 0.8761 \cdot 1 0 ^{3} \cdot 2.2 \cdot 1 0 ^{- 6}}

\frac{x - 1}{x + 5} > 2

2.6 = - 5.2 (3.4 + m)
