factor x^2-16x-80

factor

x^{2} - 16 x - 80

(x + 4) (x - 20)

Solution steps

x^{2} - 16 x - 80

Break the expression into groups

= (x^{2} + 4 x) + (- 20 x - 80)

Factor out

x

from

x^{2} + 4 x : x (x + 4)

Factor out

- 20

from

- 20 x - 80 : - 20 (x + 4)

= x (x + 4) - 20 (x + 4)

Factor out common term

x + 4

= (x + 4) (x - 20)

2 \cdot 32 - 24 + (5 - 2 \cdot 3)^{\frac{1}{1}}

\frac{5}{8} + \frac{3}{4} - \frac{1}{6} - \frac{2}{3}

6 x^{2} + 7 x - 3

(\frac{3 x ^{2}}{9 x ^{- 1}}) (6 x y)

∣ x + 3 ∣ = 7
